Section I
Paragraphs 1-1 to 1-4
SECTION I
GENERAL INFORMATION
1-1. DESCRIPTION.
1-2. The Hewlett-Packard Company Model 130C
Oscilloscope (shown in Figure 1-1) is a versatile
instrument for laboratory, production line, or indus-
trial process measurements. Horizontal and vertical
display sensitivity is 200 microvolts per centimeter
and the measurement bandwidth is 500 kc. A sweep
magnifier of up to X50 allows expansion of a trace to
the equivalent of 500 centimeters for viewing waveform
details. Single sweep operation is also provided to
allow observation of single shot phenomena or random
occurrence events. Trigger adjustments are minimized
by using either a front panel trigger-level control with
preset stability or automatic triggering which provides
a base line even with no input signal. Also, for fast,
expanded sweep times where the automatic trigger
baseline would be too dim, a free run mode may be
used to provide a bright base line display. An off-
screen trace may be easily located by depressing a
front panel Beam Finder Button which returns the
trace to the screen regardless of intensity, balance,
or position settings. Careful engineering design of
the Model 130C has resulted in high stability of gain
and minimal DC drift. The Model 130C has an internal
graticule CRT, which eliminates parallax ambiguity

and minimizes reflections and glare. The instrument
is packaged in the modular cabinet, allowing quick,
easy conversion to rack mounting and also provides
easy accessibility to internal circuits for maintenance.
1-3. MANUAL IDENTIFICATION AND CHANGES.
1-4. Information in this manual applies directly to
Model 130C instruments with a serial prefix of 445-
(see manual title page). The serial prefix of a
instrument is the first three digits (i.e. those before
the dash, as XXX-00000) of the serial number stamped
on a plate attached to the rear panel. Appendix 1
contains information on changes required to adapt
this manual to an instrument with any serial prefix
listed there. A separate change sheet (included with
this manual) provides information to adapt this manual
to an instrument with any serial prefix other than those
mentioned in this paragraph or Appendix 1. Any errors
in this manual when it was printed are called ERRATA,
and these corrections will appear only on the separate
change sheet included.
Note: Instruments with serial prefix 226-,
235-, or 248- require a different manual,
written for the 235- prefix (* Stock No.
130C-901), for correct information.

ready for use as a bench instrument. The hardware
necessary to rack-mount the instrument is packaged
with the instrument: 1) Remove tilt stand and plastic
feet, 2) Remove adhesive-backed trim strip from
sides, 3) Attach filter strip along bottom of front
panel, 4) Attach mounting flanges to sides with larger
notch toward bottom of instrument.
2-6. COOLING.
2-7. Leave at least two inches clearance around the
instrument for free circulation of air. In enclosed rack
installations, be sure that the recirculation of warm
air does not result in a high ambient temperature.
2-8. POWER REQUIREMENT.
2-9. The Model 130C operates on 115 or 230 volts
?10%, 50 to 1000 cps, single phase. The power re-
quired is approximately 90 watts. Before connecting
the instrument to the power source, be sure that the
115-230 switch on the rear panel is in the proper
position for the power source to be used. The line
fuse is mounted behind the rear panel, and is acces-
sible by removing the top cover. The 2 ampere fuse
supplied is for either 115 or 230 volt operation.
2-10. INSTRUMENT GROUND.
2-11. To protect operating personnel, the National
Electrical Manufacturer's Association recommends
that the instrument panel and cabinet be grounded.
The Model 130C is equipped with a three-conductor
power cable which grounds the instrument when an
appropriate outlet is used. The round pin on the
power cable is the ground pin connection. To retain
the protection feature when operating the instrument
from a two-contact outlet, use a three-conductor to
two-conductor adapter and connect the adapter wire
to a suitable ground.
2-12. REPACKAGING FOR SHIPMENT.
2-13. SUGGESTED PACKING MATERIALS. Topack-
age an instrument for shipment, some types of original
packing materials may be reused, or your Field
Engineer will help in getting suitable packaging. The
types of original packing materials which may gener-
ally be reused are: (1) foam which encloses the instru-
ment, (2) cardboard layers separated by foam supports,
and (3) laminated cardboard cut to desired packing
shape. Original packing materials which are a card-
board "accordion-like" filler are not recommended
for shipment since the cushioning qualities are usually
gone after one use. If packing materials recommended
above are not available, first protect the instrument
surfaces with heavy paper or sheets of cardboard
flat against the instrument. Then place instrument in
a durable carton, pad all sides with approximately
4 inches of new material designed specifically for
package cushioning, mark carton clearly for proper
handling, and insure adequately before shipping.
2-14. SHIPMENT FOR SERVICE OR REPAIR. If an
instrument is being returned to Hewlett-Packard
Company for servicing or repair, attach a tag to the
instrument specifying owner, desired action, model
number, and serial number. Ship the instrument to
Customer service at the address on the warranty
page. All correspondence should refer to an instru-
ment by Model number and the full (eight-digit)
serial number.
2-15. INSTALLATION OF AMBER FILTER.
2-16. An amber filter (( Stock No. 120A-83A) is
supplied with the Model 130C, Option 07. This filter
may be used to improve the long persistence charac-
teristics desired for observing single-shot or very
low frequency displays. To install the filter remove
CRT bezel and proceed as follows:
a. Set filter into bezel, aligning the large rectang-
ular slots in the filter edge with guides in the bezel
casting and sliding the filter down into the casting.
b. Loosen the clamp at the CRT socket. Carefully
push the CRT toward the rear of the instrument to
provide clearance for the thickness of the filter
(approximately 1/8 inch).
c. Re-install the bezel and slide CRT forward until
light mask on front of CRT just touches filter.
d. Tighten clamp to keep CRT from rotating.
Note: Over-tightening clamp may damage CRT.
e. Check alignment of trace with graticule. If
necessary adjust R329 Trace Align (rear panel).

SECTION III
OPERATION
3-1. INTRODUCTION.
3-2. The Model 130C may be used in either of two
basic modes of operation: (1) external signal to vertical
input with internal horizontal sweep or (2) external
signals into both horizontal and vertical inputs. The
deflection sensitivity and bandwidth of the two ampli-
fiers is indentical and the input to each amplifier may
be easily changed to allow either single-ended inputs
or balanced inputs. A choice of either AC or DC
coupling, at the input and internally in the amplifier,
is provided for both horizontal and vertical circuits.
The internal horizontal sweep has 21 calibrated sweep
times from 11Asec/cm to 5 sec/cm with a vernier for
continuous coverage which can extend the slowest
sweep speed to 12.5 sec/cm. Each sweep time may
be magnified by choosing either X2, X5, X10, X20,
or X50 range. The sweep can be triggered internally
from the vertical deflection signal or the line fre-
quency; external triggers can also be used, either
AC or DC coupled to the sweep circuit. See Para-
graph 3-16 for a brief operational check.
3-3. FRONT AND REAR PANEL
FAMILIARIZATION.
3-4. FRONT PANEL. Figures 3-1 and 3-2 identify
and briefly describe the Model 130C front panel con-
trols, connectors, etc. To aid in proper operation,
:Paragraphs 3-6 through 3-15 provide a more extensive
description of some front panel controls. Note that
controls for vertical and horizontal inputs are identical
in function and appearance except that the horizontal
SENSITIVITY has six internal sweep positions.
3-5. REAR PANEL. The power cord connector,
line fuse, and 115-230 volt switch are described in
:Paragraph 2-8. TRACE ALIGN is a screwdriver
adjustment to align the CRT trace with the graticule.
Relocating or reorienting the instrument within a
magnetic field such as the earth's field may require
adjustment of this control to maintain exact alignment.
The Z AXIS INPUT allows trace intensity modulation
by applying a modulating signal with the shorting link
removed. At normal trace intensity (set on front
panel), a +20 volt pulse will blank the trace. If not
using the Z AXIS INPUT terminals, be sure the
shorting link is in place.
3-6. SENSITIVITY.
:3-7. SENSITIVITY control (vertical or horizontal)
sets the deflection sensitivity of the display in milli-
volts per centimeter or volts per centimeter, when
VERNIER is in CAL. position. In BAL position of
the SENSITIVITY switch, the amplifier input is
grounded and the input terminals are opened, to
facilitate setting of the amplifier DC balance (see
Paragraph 3-8 and Figure 3-3). In the CAL. position,
an internal calibrator signal is applied to the amplifier
input and the calibration accuracy can be checked by
noting the deflection on the CRT as follows: (1) with
no vertical input, when HORIZONTAL SENSITIVITY
and VERNIER are set to CAL, a horizontal line 5 cm
long should be displayed (if not the probable cause is
misadjustment of the horizontal gain; see Section V),
(2) with no horizontal input, when VERTICAL SENSI-
TIVITY is set to CAL, a vertical line 5 cm long should
be displayed (if not, the probable cause is misadjust-
ment of the vertical gain; see Section V); if an internal
sweep time is used a 5 cm p-p square wave should be
displayed. The INTERNAL SWEEP positions of
HORIZONTAL SENSITIVITY can be used to effectively
expand a trace from two screen diameters in X2 to
fifty screen diameters in X50.
3-8. DC BALANCE.
3-9. The DC BALANCE control has a range of about
40 screen diameters, i.e. it can effectively move
the trace about 400 cm. Its purpose is to set internal
amplifier operating conditions such that there is a
minimum trace shift as SENSITIVITY is switched
from range to range, or when VERNIER is used.
This is especially important at the more sensitive
ranges (toward 0.2 MV/CM) when the AMPLIFIER
switch is set for DC coupling. Figure 3-3 provides
the procedure for setting vertical and horizontal DC
BALANCE properly. The setting may change during
warmup or extended periods of operation and require
periodic readjustment when the instrument is used
DC coupled at high sensitivities.
DC BALANCE is a "fine" control and should
additional range be required to balance the
amplifier a coarse DC balance adjustment
is located within the instrument (see Section
V for procedure).
3-10. LEVEL.
3-11. Through its variable range, LEVEL control
determines the point on the triggering-source wave-
form at which the sweep starts. This trigger level
is variable whether using external, internal, or line
for the trigger source. By proper setting of LEVEL
the sweep may be started at any point on a vertical
deflection waveform (deflection > 0.5 cm) when trig-
gering internally or at a point between +10v to -10v
on an external trigger signal. The + or - on the
LEVEL control refers to the direction the triggering
point moves on a waveform, regardless of the SLOPE
setting (for example, turning LEVEL ccw moves
triggering level toward a more negative point on the
triggering waveform). When LEVEL is set fully
counterclockwise to AUTO (detented position), the
sweep will free run at a low repetition rate providing
a baseline in the absence of a triggering signal and
then provide automatic triggering of the sweep when
a signal within specifications is applied. In AUTO an
external trigger is always AC coupled. When LEVEL
is set fully clockwiseto FREE RUN (detented position),

the horizontal sweep is free running at a rate deter-
mined by the sweep time setting, and cannot be con-
trolled by a triggering signal.
3-12. NORMAL-SINGLE.
3-13. When NORMAL-SINGLE is set to NORMAL, the
horizontal sweep operates recurrently as determined
by the triggering signal. In SINGLE position, the
sweep can be triggered only once, after which it is
locked out until armed by switching to NORMAL and
back to SINGLE. The ARMED light is on in SINGLE
position when the sweep is armed and ready to be
triggered. To use the single sweep operation, LEVEL
must be set anywhere in its variable range, i.e. not
in AUTO or FREE RUN. See also Paragraph 3-24.
3-14. BEAM FINDER.
3-15. This paragraph will explain operation and
function of the BEAM FINDER and also discuss some
causes of no CRT display. The BEAM FINDER push-
button is useful for locating a display which is not
visible on the CRT for these common reasons: 1) DC
unbalance in amplifier at high sensitivities, (and
AMPLIFIER DC coupling), 2) amplifier being over-
loaded at input, or 3) intensity set too low. Depressing
the BEAM FINDER defocuses and intensifies the CRT
trace (or spot), and reduces the sensitivity of both
horizontal and vertical amplifiers so the trace appears
on-screen regardless of INTENSITY, DC BALANCE,
and POSITION settings. The beam finder reduces
amplifier gain enough to overcome the effective posi-
tioning range of the DC BALANCE controls, which
amounts to as much as 40 screen diameters (i.e.
400 cm) at the highest amplifier sensitivity, as com-
pared to only 2 screen diameters (20 cm) range for
POSITION control. Because of the desensitization
required to overcome DC BALANCE range, the POSI-
TION controls are essentially inoperative when the
BEAM FINDER is depressed. Therefore, always set
POSITION to approximately "12 o'clock" before using
the beam finder. To get maximum usefulness from
the BEAM FINDER, the selected amplifier sensitivity
and coupling should also be considered. At higher
amplifier sensitivities (i.e. toward 0.2 MV/CM), if
AMPLIFIER is set to AC, a DC unbalance in the
amplifier cannot cause an off-screen deflection. In-
stead, the most probable cause is amplifier overload
by the input signal or intensity maybe set too low. At
higher sensitivities with amplifier DC coupling, and
trace not on screen, switch AMPLIFIER to AC and if
trace now appears on-screen then a DC unbalance
exists (to make DC BALANCE setting see Figure 3-3).
At lower amplifier sensitivities, DC unbalance is
eliminated as a cause for off-screen trace. Another
cause of no display is non-triggering sweep and this
can be checked by noting if trace appears when the
automatic triggering mode is used (see Table 1-1 for
specifications).
3-16. OPERATIONAL CHECK.
3-17. This procedure may be followed to checkopera-
tion of most controls and circuits of the Model 130C.
a. Turn INTENSITY to about 12 o'clock position
(turns AC power on). Allow several minutes warmup.
b. Set all VERNIERs to CAL.
c. Set horizontal and vertical AMPLIFIER and
INPUT to AC.
d. Set vertical SENSITIVITY to CAL.
e. Set the horizontal SENSITIVITY to INTERNAL
SWEEP X1 and set SWEEP TIME to 1 MILLISECONDS/
Cm.
f. Set TRIGGER SOURCE-SLOPE to INT. +, LEVEL
to AUTO, and NORMAL-SINGLE to NORMAL.
g. Adjust both POSITION controls' to center display.
Adjust FOCUS for sharp, clear trace.
h. The height of the square wave displayed should
be 5 cm.
3-18. OPERATING PROCEDURES.
3-19. Paragraphs 3-20 through 3-29, and the figures
referenced, describe procedures for various opera-
ting modes and applications of the Model 130C. Before
operating the Oscilloscope and following these pro-
cedures, it is recommended that Paragraphs 3-3
through 3-15 be read to become completely familiar
with front panel controls. Also, Paragraphs 3-31 and
3-33 describe considerations which are important in
most measurements with the Model 1300
3- 20. INTERNALLY TRIGGERED SWEEP
OPERATION.
3-21. In this type operation, the sweep is triggered
internally from the vertical signal or line frequency
and the signal to be observed is applied to the vertical
input; Figure 3-4 provides a step by step procedure.
With TRIGGER SOURCE-SLOPE set to INT. + or -,
the sweep is triggered when the vertical signal input
causes a vertical deflection of 0.5 cm or more. With
TRIGGER SOURCE-SLOPE set to LINE + or -, the
sweep is triggered from the AC power line waveform.
Function of LEVEL control is described in Para-
graph 3-10.
3-22. EXTERNALLY TRIGGERED SWEEP
OPERATION.
3-23. In this type operation the sweep is triggered
from an externally applied signal and the signal to be
observed is applied to the vertical input; Figure 3-5
provides the step by step procedure. With TRIGGER
SOURCE-SLOPE set to EXT. + or -, the horizontal
sweep is triggered by a signal of 0.5V p-p or more,
applied to the trigger input terminals. Figure 3-5
explains use and specifications for AC or DC trigger
input coupling; if LEVEL is set to AUTO, the external
trigger signal is always AC coupled. Function of
LEVEL control is explained in Paragraph 3-10.
3-24. SINGLE SWEEP OPERATION.
3-25. A step by step procedure for obtaining single
sweep operation is contained in Figure 3-6. This
method is useful for observing single shotphenomena
or random events. With single sweep operation, the
sweep occurs just once and cannot beretriggereduntil
manually rearmed. See also Paragraph 3-12 for
explanation of the SINGLE-NORMAL switch.

3-26. DIFFERENTIAL INPUT OPERATION.
3-27. Balanced inputs are provided on all SENSI-
TIVITY ranges of both horizontal and vertical deflec-
tion amplifiers which allows measurement of the
difference between two signals. This is called dif-
ferential input operation and in this mode the two
signals are subtracted algebraically and the differ-
ence is displayed as a single trace. This type of
operation eliminates signals which are common to both
inputs (referred to as the common mode signal) and
displays signals peculiar to only one input. Figure
3-7 provides a step by step procedure for differential
operation of the Model 130C. Common mode rejection
expressed in decibels represents the ability of the
amplifier to attenuate the common mode signal and
this is summarized in Table 3-1 along with the maxi-
mum allowable peak-to-peak common mode signal to
maintain these rejection ratios.

3-28. X-Y OPERATION.
3-29. In the X-Y mode of operation the internal sweep
is disabled and external signals are applied to both
the horizontal and vertical amplifiers. Figure 3-8
provides an operating procedure for obtaining Lissa-
jous patterns or X-Y plots. The X-Y display is a
graph of the vertical signal vs. the horizontal signal
and is useful for displaying plots of voltage vs. current,
hysteresis loops, pressure vs. strain ( using strain
gages), etc. Another important application for X-Y
operation is to make phase shift measurements. The
vertical and horizontal amplifiers have identical
characteristics and less than ?1? relative phase shift
from DC to 100 kc when VERNIERs are set to CAL.
and amplifier SENSITIVITY settings are equal.
Application Note 29 describes a convenient method
for measuring phase shift. When measuring phase
shift at very low frequencies, use both AMPLIFIER
DC and INPUT DC to eliminate phase differences
contributed by the AC coupling capacitors.
3-31. USE OF AMPLIFIER AND INPUT AC-DC.
3-32. Different combinations of AMPLIFIER and IN-
PUT coupling will provide various advantages in the
characteristics of operation depending on the wave-
form to be displayed. Table 3-2 summarizes the
typical low-frequency 3 db cutoff point with different
SENSITIVITY and coupling settings; typical applica-
tions are also given. The high frequency 3 db cutoff
point is 500 kc in all cases. For SENSITIVITY settings

coupling switch has no effect; coupling is always DC
for these ranges. When using amplifier AC coupling
in the most sensitive range of 0.2 MV/CM at low
ambient temperatures the amplifier sensitivity is
reduced slightly. The reduction is noticeable only at
temperatures below 25?C and reaches a maximum of
approximately 3% at 0?C.
3-33. APPLYING INPUT SIGNALS.
i3-34. For measurements at high amplifier sensi-
tivities and high impedance levels a shielded input
connection to the Oscilloscope is desirable. The
Model 10111A Adapter provides a shielded banana
post to female BNC connector. Two adapters can be
used to provide shielded connections for differential
input operation. Frequency compensated divider
probes (listed in Table 1-2) can be used to provide
a higher input impedance and thus reduce loading
effects on the circuit where measurements are made.
The 500 MV CALIBRATOR output on the Model 130C
front panel may be used for probe compensation adjust-
ment (described in the Operating Note for the probe).
The Model 1011 1A Adapter is necessary for connecting
the divider probes to the Model 130C input terminals.

SECTION IV
PRINCIPLES OF OPERATION
4-1. INTRODUCTION.
4-2. As shown in the block diagram, Figure 4-1, the
Model 130C consists of five major sections: low voltage
power supply, high voltage power supply, vertical
amplifier, horizontal amplifier and sweep generator.
4-3. The paragraphs of this section discuss the
circuit details of the major sections of the Model 130C.
Since the vertical and horizontal amplifiers are nearly
identical, the horizontal amplifier is described where
it differs from the vertical amplifier.
4-4. LOW VOLTAGE POWER SUPPLY.
4-5. The low voltage power supply provides operating
voltages for the amplifiers and for the sweep generator
circuits with outputs of -100V, +12.5V, +100V, and
+250V. The regulated +12.5 volt supply provides fila-
ment voltage for the vertical and horizontal input stages
and a current source for the trace alignment coil.
4-13. The high voltage power supply provides the
voltages necessary for the operation of the cathode
ray tube. Refer to Figure 4-3 for the following ex-
planation. Tube V301 is operating in a Hartley oscil-
lator circuit, oscillating at approximately 70 kc.
The oscillator voltage is applied to the primary of
high voltage transformer T301. The primary voltage
is stepped up by the transformer and rectified by
V304 and V305. The outputof the rectifiers is filtered
and applied to the CRT cathode and grid. The CRT
cathode voltage is compared to the +250V supply by
voltage dividers R311 through R318 and applied to
Control Amplifier V302. Since the cathode of V302 is
4-6. -100 VOLT SUPPLY.
4-7. The -100 volt supply provides regulated voltages
for the amplifier and sweep circuits, and also provides
a reference voltage for the +100 volt and +250 volt
supplies. Refer to Figure 4-2. Differential Amplifier
Q463/Q464 compares the reference voltage from
Reference Tube V461 against the output voltage sample
obtained by voltage divider R467/R469. The differ-
ence voltage is amplified and applied to Driver Q462
and Series Regulator Q461. The voltage applied to
Series Regulator Q461 is out of phase, i.e., when the
output voltage of the supply rises, the voltage applied
to Q461 causes the series voltage drop to increase,
returning the supply voltage to its original level. In
this way, any variations in output voltage due to load
change or line voltage change are sensed by the differ-
ential amplifier and corrected by the series regulator.
Potentiometer R468 adjusts the output voltage to
exactly -100 volts.
4-8. +100 and +250 VOLT SUPPLIES.
4-9. The +100 and +250 volt supplies operate in the
same manner as the -100 volt supply. A sample of
the output voltage is compared to a reference voltage
(the -100 volt supply) and the difference voltage ampli-
fied and applied to a series regulator. The series
regulator corrects for the variations in output voltage.
The +250 volt is "stacked" on the +100V supply and
the two are interdependent.
4-10. +12.5 VOLT SUPPLY.
4-11. The +12.5 volt supply is dependent only on the
-100V supply and uses a single series regulator Q481
with a Zener diode reference CR482. Any variation
in supply voltage is coupled through the reference
diode. This results in a base current change for Q481,
which is amplified and acts to vary the supply load

tied to a regulated voltage (-100 volts) any variation
in high voltage is seen by V302 as a change in grid-
cathode voltage. This grid-cathode voltage change is
amplified and applied to the screen grid of Oscillator
V301 to control the output amplitude of the oscillator.
The change is always in the proper direction to cor-
rect for change in high voltage.
4-14. INTENSITY control R308 varies the CRT cath-
ode voltage, varying the intensity of the spot or trace
on the CRT screen. FOCUS control R317 varies the
focus grid voltage for trace focus. Astigmatism
adjustment R319 varies the voltage on the accelerator
to adjust beam geometry for a round spot.
4-15. SWEEP GENERATOR.
4-16. Refer to Figure 4-4 for a block diagram of the
sweep generator circuitry. The trigger generator
produces signals which synchronize the sweep with
internal signals from the vertical amplifier or power
line, or with external trigger signals. In Figure 4-4
circuits represented in blocks to the right of the Trig-
ger Generator produce a linear sweep voltage (saw-
tooth wave shape) which is amplified by the horizontal
amplifier and applied to the CRT deflection plates.

signal, whether power line, internal, or external, is
applied to one grid of V101 as determined by setting
of the trigger slope control (S101). The other grid is
connected to LEVEL control R116 through 5101. The
setting of R116 determines the DC level on one half
of V101, and thus the point at which the trigger signal
will cause V101 to conduct. The output of V101B
drives trigger generator V102 which provides the
waveform to drive the gate generator. When S102 is
in FREE RUN no trigger is needed to switch the gate
generator to start a new sweep; see Paragraph 4-26.
When S102 is in AUTO, trigger generator V102 is
converted to a free-running multivibrator (R124 is
placed in circuit by S102C), with a repetition rate of
40 to 50 cps. Switch section S102B grounds one grid
of V101 (depending on slope selected by 5101) and
AC-couples the trigger signal through C113 to V102A.
This arrangement allows the trigger to be generated
at the approximate zero crossing of the input signal.
4-19. GATE GENERATOR.
4-20. The square wave generated by V102 is differ-
entiated by C115 and R130, and the positive spike is
clipped by CR111. Gate Generator V103A and V104B
operates as a Schmitt Trigger circuit with wide
hysteresis limits. The negative spike, through C116
to the grid of V103A, causes the gate generator to
change states, starting the sweep. As the gate gen-
erator switches states, the positive output at V103A
plate goes to cathode follower V104A which provides
the unblanking signal to the CRT (through the HV power
supply) .
4-21. INTEGRATOR.
4-22. As the gate generator changes stages (on signal
from the trigger generator), the negative gate voltage
at V 104B takes diodes V 109A and V 109B out of con-
duction. This allows the timing capacitor (C175
through C181, depending on sweep time set) to charge
in a negative direction, since it is connected through
the sweep time resistors to -100 volts. The integrator
V106A amplifies and inverts this negative-going volt-
age at its grid (pin 2) to produce a large, positive-
going output at the plate. This positive-going voltage
is fed back to V106A grid through cathode follower
V106B and the timing capacitor and this feedback
]seeps the integrator input voltage almost constant.
Thus the voltage across the sweep timing resistor
also remains nearly constant to produce a correspond-
ing nearly constant current. The current charges
the sweep capacitor at a linear rate to produce a
linear sweep output. The sweep output is routed
through switch S202 to the horizontal amplifier and
then to the CRT deflection plates.
4-23. The slope of the sweep output waveforms is
determined by the RC time constant of resistors
(R175 to R186) and capacitors (C175 to C181) used on
a selected SWEEP TIME range. VERNIER control
It179 provides a fine adjustment of sweep time by
altering the DC voltage to which the timing resistor
is returned. Neon lamp V107 is used to reduce the
average level of the sawtooth swing to a less positive
value so the lower end of the sweep may be clamped
to zero volts.
Section IV
Paragraphs 4-19 to 4-27
4-24. SWEEP TERMINATION AND HOLD-OFF.
4-25. Termination of a sweep is accomplished by
feeding back the positive-going sweep voltage to the
input of the gate generator. The feedback path is
through hold-off diode V109C (which conducts during
the sweep) and hold-off cathode follower V103B. The
feedback voltage on V103B grid causes the cathode
voltage to cross the upper hysteresis limit of the gate
generator. The time required for this feedback to
reach the upper hysteresis limit is determined by the
sawtooth slope, thus setting the time between sweeps.
The gate generator changes state to produce a neg-
ative voltage step at the plate of V103A and a positive
voltage step at the plate of V104B. The negative volt-
age step is fed through gate output cathode follower
V104A to the high-voltage power supply, blanking the
CRT beam until a new sweep begins. The positive
voltage step at the plate of V104B causes diodes V 109A
and V109B to conduct. The sweep timing capacitor
discharges quickly through the clamp diode V109B,
clamping the sweep output to a constant level and
producing the retrace portion of the sweep waveform.
The two diodes return the sweep output to the same
reference level as the gridof integrator V106A. Hold-
off diode V109C is cut off by the fast negative drop of
the retrace (i.e., as timing capacitor discharges), but
instead of a rapid decrease in voltage at the grid of
V103B, the voltage here starts decaying at a rate
determined by R148 and the value of hold-off capacitor
used on a given sweep range. The cathode of V103B
follows this decay rate and V103A grid voltage is kept
high enough for a sufficient time to allow sweep circuit
recovery. When the hold-off level from V103B decays
enough, a negative trigger at V103A grid can reach
the lower hysteresis limit and begin a new sweep cycle.
Stability adjustment, R151, sets the DC level (just
above lower hysteresis limit) at which V103B cathode
quits following the hold-off decay voltage on the grid
(this circuit is changed in free run operation; see
Paragraph 4-26). An incoming trigger which reaches
below this DC level to the lower hysteresis limit,
starts the new sweep.
Note
The hold-off capacitor for a given sweep time
setting is the same capacitor which is used
as the timing capacitor in another sweep
range (except that stray capacitance is used
for hold-off purposes in the three fastest
sweep speeds). For example, C176 is the
hold-off capacitor in 0.1 through 5 SECOND/
CM settings, but then C176 becomes the
timing capacitor in 10, 20, and 50 MILLI-
SECONDS/CM settings (and C177 becomes
the hold-off capacitor).
4-26. FREE RUN CIRCUIT OPERATION.
4-27. When LEVEL control is set to FREE RUN, the
gate generator and other sweep circuits operatewith-
out a trigger from V102. This is accomplished by
allowing the hold-off decay at V103B cathode to cross
the lower hysteresis limit (rather than a trigger
crossing as explained in Paragraph 4-24) of the gate
generator which initiates a new sweep cycle. The
stability adjustment is switched out of the circuit by
S102E which applies -100 volts directly to R152 in the

cathode circuit of V103B. This shifts the DC level
at which V 103B cathode quits following the grid hold-
off voltage to a level below the lower hysteresis
limit. Now as the hold-off decay voltage crosses
the hysteresis limit it starts the sweep again.
4-28. SINGLE SWEEP CIRCUIT.
4.-29. In single sweep operation the sweep is triggered
on the first trigger received after manual. arming,
and further triggers are ineffective until the circuit
is re-armed. This sequence is accomplished in the
Model 130C by preventing the retrace from occurring.
In NORMAL operation, switch S104A returns Q101
emitter to ground through R150 and the transistor is
inoperative. In SINGLE operation, however, S104A
connects R150 to -100 volts. This still biases Q101
off, but allows conduction when the base voltage be-
comes more positive during the sweep. In the SINGLE
position, S104B connects +100v to neon indicator
D S101. Because the sweep level is at zero volts be-
fore the sweep waveform begins, there is sufficient
voltage across the neon to cause it to light (ARMED).
Assuming that S104 has just been switched to SINGLE
position, the first trigger to arrive at the gate gener-
ator starts a sweep in the usual way. As the sweep
output voltage rises, the voltage across DS101 de-
creases until the light goes out. The positive-going
sweep voltage is also applied by voltage divider R143
and R144 to the base of Q101, bringing the transistor
into conduction and eventually driving it into satura-
tion. As in NORMAL operation, the sweep voltage is
fed back through the hold-off circuit to switch the gate
generator back to its pre-sweep condition (V103A on,
V104B off). With V104B cutoff, the saturation current
of Q101 flowing through R137 is still enough to keep

diodes V109A and V109B biased off. Integrator V106A
is thus allowed to continue integrating until it reaches
saturation. The sweep output waveform rounds and
levels off, remaining at this high positive level until
the circuit is manually re-armed. Since this positive
voltage is fed back through the hold-off circuit to the
input of the gate generator, triggers generated by
V102 are unable to overcome this voltage and operate
the gate. To re-arm the circuit, S104 is switched
back to NORMAL. This cuts off Q101, which allows
V109A and V109B to conduct and return the integrator
to its pre-sweep condition. Setting switch S104 back
to SINGLE will repeat the single sweep operation.
4-30. VERTICAL AMPLIFIER.
4-31. The vertical amplifier, as shown in the block
diagram of Figure 4-5, consists of three basic sec-
tions: (1) input attenuators, (2) differential feedback
amplifier, and (3) output differential amplifier. These
circuits are explained in detail in Paragraphs 4-32,
4-34, and 4-36.
4-32. INPUT ATTENUATOR.
4-33. The input attenuator consists of two identical
frequency-compensated voltage dividers which pro-
vide a constant input impedance of 1 megohm shunted
by 45 pf on all ranges of SENSITIVITY for both + and -
inputs. Switch S2 selects either capacitive (AC) or
direct (DC) coupling from the input terminals to the
attenuator. Capacitors C21 and C22 areusedto adjust

ratio of 100:1 on the three least sensitive ranges
(5 VOLTS/CM to 20 VOLTS/CM) is provided by
R11/R13 and R12/R14 on the two inputs. Capacitors
Cll and C12 maintain the ratio at high frequencies
by capacitive division. Capacitors C13 and C14 are
adjusted for 45 pf input capacitance on the three least
sensitive ranges. A division ratio of 10:1 on the next
three ranges (0.5 VOLTS/CM to 2 VOLTS/CM) is
provided by R15/R17 and R16/R18 on the two inputs.
Capacitors C17 and C18 maintain this ratio at high
frequencies and C19 and C20 are adjusted to keep
input capacitance at 45 pf on these three ranges. In
the CAL. position of the SENSITIVITY switch, input
terminals are opened and a 5 millivolt, ?3%, 350 cps
square wave is applied to the input of tube ViA to
check amplifier calibration. Sensitivity of the ampli-
fier in the CAL. position is 1 my/cm. In BAL. posi-
tion, the input terminals are opened and the grid
circuits of V1 are grounded to allow accurate balanc-
ing of DC voltages in the amplifier.
4-34. DIFFERENTIAL FEEDBACK AMPLIFIER.
4-35. From the input attenuator, a signal is fed to
the input of the differential feedback amplifier, i.e.
grids of Vl. Resistors R41 and R42 provide input
overload protection. The gain of this amplifier
(consisting of V1, and Q1 through Q4) is effectively
controlled by the interstage attenuator which inserts
feedback resistance (determined by Si setting) be-
tween the emitters of Q3 and Q4. Gain is propor-
tional to the ratio of the third-stage (Q3 and Q4) col-
lector load to feedback resistance. The interstage
attenuator and the input attenuator give the overall
control of deflection sensitivity. The main DC current
path for both V1 and Vernier Bal adjustment is through
the feedback paths, R49-R50 or R48, to the -100 volt
supply at the collectors of Q3 and Q4. The positive
voltage supply with high value resistors (compared
to feedback resistance) used for Vernier Bal, mini-
mizes the effect of balance adjustments on gain.
Vernier Bal is adjusted to offset any unbalance at the
output stage plates resulting from the change in re-
sistance between the cathodes of V2A and V2B when
VERNIER is rotated out of CAL position. DC BAL-
ANCE, R49, and Coarse DC Bal, R48, adjustments
are used to equalize the voltage on either side of the
feedback resistance. When the voltages are balanced,
the feedback resistors have no DC flowing through
them and thus changing their values has no effect on
amplifier balance. Variable resistor R59 sets Q3/Q4
collector voltages for an average of -15 volts, ensuring
linear operation of the output differential amplifier.
The AMPLIFIER AC-DC switch allows capacitive
coupling of the interstage attenuator on the seven most
sensitive ranges, minimizing the effect of dc drift by
preventing DC current flow in the feedback resistors.
The result is the same as if the amplifier is balanced.
Gain adjustment R69 functions in the same manner as
VERNIER control R70, by inserting resistance which
acts as degenerative feedback. Thus the gain may be
controlled in order to bring the sensitivity calibration
into agreement with a voltage standard or to set inter-
mediate sensitivities. The output of the differential
feedback amplifier at Q3 and Q4 collectors drives the
output differential amplifier, V2A and V2B.
4-36. OUTPUT AMPLIFIER.
4-37. The output differential amplifier, V2A and
V2B, provides the voltage swing necessary to drive
the deflection plates of theCRT. Cross-neutralization
of the output stages is accomplished by adjustable
capacitors C48 and C49 (shunted by C53), which
couple in-phase signals from the plates of the tubes
to the opposite grids. A voltage divider consisting
of R75 and R77 in the plate circuit of V2A divides
the output signal for use as an internal synchronizing
signal for the sweep generator. Constant current
source V3 is an active impedance, functioning as a
high common cathode impedance to achieve high
differential gain without the use of a large cathode
resistor and negative supply. Resistor R83 sets the
bias on V3, hence the current to the output differential
amplifier. The setting of R83 interacts with R59.
There are two front panel variable controls in the
output amplifier: SENSITIVITY VERNIER and POSI-
TION. When rotated ccw VERNIER, R70, decreases
the gain (i.e. reduces sensitivity) of the amplifier by
introducing degeneration in the cathodes of V2. Ver-
tical movement of the trace is accomplished by POSI-
TION, R78, which feeds back differential currents
through R73 and R74. This results in a differential
change in Q3 and Q4 collector currents and a differ-
ential voltage change at the grids of V2. Resistors
R79 and R80 ensure that regardless of the POSITION
setting, no DC voltage change occurs at the cathodes
of V2 as VERNIER is moved. Thus, position of the
trace is not affected by changes in the SENSITIVITY
VERNIER.
4-38. BEAM FINDER switch S4 inserts R85 in the
cathode of V3, reducing the current available to the
output stage. This reduces the voltage swing of V2
and reduces the CRT deflection plate voltage swing,
which brings the trace on screen regardless of signal
amplitude.
4-39. HORIZONTAL AMPLIFIER.
4-40. The horizontal amplifier circuit operation is
identical to that of the vertical amplifier except for
the internal sweep positions of the SENSITIVITY
switch, and the POSITION control R221A/B. In the
INTERNAL SWEEP positions, Xl through X50, the
sawtooth voltage output from the sweep generator is
coupled into the amplifier input at V201A. The sweep
signal gain is then controlled by the interstage attenu-
ator (see Figure 5-16) and applied to the CRT deflec-
tion plates. To allow viewing of any portion of an
expanded waveform, a greater range for POSITION
control is obtained by varying the DC level at the
amplifier input where the sweep is applied. For in-
ternal sweep, R221B is switched out of the circuit
and replaced by two fixed resistors, R273 and R274;
VERNIER R264 is also shorted out leaving V202
cathodes tied together. Resistor R221A (and its
voltage divider circuit) becomes the POSITION control
and changes the DC level at which the sweep wave-
form is applied to the amplifier. Then as amplifier
gain is increased by the interstage attenuator section
of S202, the sweep is expanded and the effective
positioning range is increased at the same time.

usually be traced to two sources: defective filter
capacitors or defective transistors. The ripple at
the output of each supply and at the input to each
regulator is given in Table 5-5. If the ripple at the
output of any of the supplies is excessive, check the
-100 volt supply first. If its output is normal, then
check the ripple at the regulator input of the supply
in question. If the ripple of the unregulated supply
is excessive, check the filter capacitors and the
rectifier diodes. If the ripple of the unregulated
supply is normal, check for defective transistors in
the amplifier series and regulator stages.
5-35. LOSS OF REGULATION.
5-36. The failure of any of the supplies is usually
due to transistor failure. Table 5-6 provides a sys-
tematic procedure for troubleshooting each of the

low voltage power supplies. The transistors associ-
ated with the low voltage supplies are located on the
low voltage power supply circuit board and at the
rear of the instrument. For the location of the circuit
board, refer to Figure 5-1.
5-37. Resistors R421, R441, R461, and R481 protect
the series regulator transistors in each of the supplies.
If the output of one of the supplies is accidentally
shorted, the resistor in series with the series regu-
lator will dissipate excessive power and fail. Check
each of the series resistors (located near the filter
capacitors; note silkscreen identifiers) when a mal-
function of the low voltage supplies is suspected.
5-38. HIGH VOLTAGE POWER SUPPLY
TROUBLESHOOTING.
f. Connect ground lead of ohmmeter to chassis.
g. Compare resistance readings at corresponding
points in both halves of the amplifier. Unsymmetrical
readings will indicate a source of unbalance.
h. If resistance readings do not point out the source
of the unbalance, proceed to step i.
i. Turn instrument on, switch AMPLIFIER to
AC and set SENSITIVITY to BAL position.
j. Measure DC voltages at corresponding points
in both halves of the amplifier.
k. Switch AMPLIFIER to DC.
m. Repeat voltage measurements made in step j.
Compare readings made in steps j and m with voltages
shown on schematics. Any significant deviation should
indicate location of the trouble.
5-39. Waveforms and DC voltages which will aid in
troubleshooting are shown on the schematic diagram.
5-40. Troubles in the high voltage power supply can
best be isolated by DC voltage measurements. Any
decrease in the regulated high voltage is amplified
and inverted by V302 and applied to V301. The screen
voltage of V301 controls the amplitude of the oscil-
lator output, and thus the high voltage.
5-41. AMPLIFIER TROUBLESHOOTING.
5-42. Since the vertical and horizontal amplifiers
are nearly identical; a single troubleshooting pro-
cedure may be used for both amplifiers.
5-43. UNBALANCE.
5-44. If the trace cannot be brought on screen with
the DC BALANCE control, try adjusting R48 in the
vertical amplifier or R234 in the horizontal amplifier.
If the trace is still off-screen, use the following
procedure to localize the unbalance.
a. Set POSITION to midrange.
b. Short grids of output tubes together (V2 in
vertical, V202 in horizontal).
c. If trace remains off-screen, trouble is in output
stage. If trace returns, proceed to step d.
d. Turn the instrument off.
5-45. GAIN.
5-46. If the gain of the amplifier cannot be set pro-
perly with Gain adjustment (R69 in vert, R263 in
horiz.), try the next higher sensitivity range. If the
gain cannot be set on this range, change V2 in vertical
amplifier or V202 in horizontal amplifier, and check
the high voltage output (ref. Paragraph 5-67).
5-47. LOW-FREQUENCY NOISE.
5-48. If low-frequency noise is visible on the trace,
try changing the input tube (V1 invert, V201 in horiz.).
If this does not cure the trouble, change the second
stage transistors (Q1, 2 in vert. Q201, 202 in horiz.).
5-49. COMPRESSION.
5-50. If the signal waveform is compressed inampli-
tude when the trace is moved to the top or bottom of
the screen, check that the output stage current is
adjusted properly (ref. Paragraph 5-74), then try
changing the output tube.
5-51. SWEEP GENERATOR
TROUBLESHOOTING.
5-52. If the horizontal amplifier is not operating
properly, the sweep operation (not sweep circuit) will
also be affected. If a sweep malfunction is observed,
first check the horizontal amplifier. If the horizontal

amplifier is operating properly check typical wave-
forms shown in Figure 5-8 (located near schematic)
proceed to the steps below.
a. Set LEVEL to FREE RUN. If thesweepoperates,
check V101, V102, and CR111. If the sweep does
not operate, proceed to step b.
b. Check DC voltage in each of the states shown
in Table 5-7. A 10 to 15% deviation from the values
shown in the table can be expected; larger deviations
indicate a source of trouble.
5-53. REPAIR AND REPLACEMENT.
5-54. Circuit boards used in the Model 130C have
components on one side of the board and a plated
conductive metal layer through component holes.
When removing or replacing etched circuit components
the important steps and considerations are($ Service
Note M-20D also contains useful information on etched
circuit repair):
a. Use a low heat (37 to 47.5 watts, less than 800?F
idling temperature), slightly bend chisel tip (1/16 to
1/8 inch diameter) soldering iron, and a small dia-
meter, high tin content solder. If a rosin solder is
used, clean the area thoroughly after soldering.
b. Components may be removed by placing the
soldering iron on the component lead on either side of
the board, and pulling up on the lead. If heat is applied
to the component side of the board, greater care is
required to avoid damage to the component (especially
true for diodes). If heat damage may occur, grip the
lead with a pair of pliers to provide a heat sink be-
tween the soldering iron and component.
c. If a component is obviously damaged or faulty,
clip the leads close to the component and then unsolder
the leads from the board.

**Reset: Connect Pin 2 of V103 to ground.
d. Large components such as potentiometers and
tube sockets may be removed by rotating the soldering
iron from lead to lead and applying steady pressure
to lift the part free (the alternative is to clip the
leads of a damaged part).
e. Since the conductor part of the etched circuit
board is a metal plated surface, covered with solder,
use care to avoid overheating and lifting the conductor
from the board. A conductor may be cemented back
in place with a quick-drying acetate base cement (use
sparingly) having good insulating properties. An-
other method for repair is to solder a section of good
conducting wire along the damaged area..
f. Clear the solder from the circuit board hole
before inserting a new component lead. Heat the
solder in the hole, remove the iron, and quickly
insert a pointed non-metallic object, such as a
toothpick.
g. Shape the new component leads and clip to
proper length. Insert the leads in the holes and apply
heat and solder, preferably on the conductor side.
5-55. Most of the wire leads to the etched circuit
boards have edge-on connectors. When removing
or replacing these connectors, be sure they are
properly aligned with the guide slot in the board edge.
Applying force with the connector mis-aligned will
spring the contacts and result in a faulty electrical
connection.
5-56. CATHODE RAY TUBE REPLACEMENT.
5-57. To replace the cathode ray tube, use the
following procedure:
Serious injury may result if the cathode ray
tube is dropped. Handle the tube carefully.
b. Loosen the clamp at the CRT socket.
c. Remove the tube socket from the clamp. It may
be necessary to carefully loosen socket from clamp
with a narrow-blade screwdriver.
d. Slide the tube out of the instrument.
e. Install the new CRT, reversing previous steps.
Note: over-tightening the clamp at the CRT socket
may damage the tube.
f. Check alignment of trace with graticule. If
trace is misaligned, bring into alignment with R329,
TRACE ALIGN (rear panel).
Check Astigmatism (ref. Paragraph 5-68).
Check Intensity Limit (ref. Paragraph 5-69).
Check Vertical Gain (ref. Paragraph 5-75).
Check Horizontal Gain (ref. Paragraph 5-75).
5-58. ADJUSTMENTS.
5-59. The adjustment procedures are divided into
three groups. Group I adjustments include procedures
of Paragraphs 5-64 through 5-69; these procedures

controls for CRT display. Group II adjustments are
in the procedures of Paragraphs 5-70 through 5-80;
these procedures are for adjustments which are made
the same way in both vertical and horizontal circuits.
Group III adjustments are in the procedures of Para-
graphs 5-81 through 5-86; these procedures adjust
the calibrator output and the sweep generator circuit,
and depend on an accurate calibration of the vertical
and horizontal circuits. Refer to Figures 5-1 and
5-2 to locate adjustable components. Always make
the preliminary settings of Paragraph 5-62 before
following any adjustment paragraph procedure.
5?-60. REQUIRED TEST EQUIPMENT.
5-61. Refer to Table 5-1 for information on instru-
ments required for the adjustment procedures. Sub-
stitute instruments should have the characteristics
described in the table.
5?-62. PRELIMINARY SETTINGS.
5?-63. The following settings must be made prior to
following any adjustment paragraph procedure. If a
setting is different from these preliminary settings,
the procedure for the adjustment will specify so.

to -.
c. Set the Voltmeter Calibrator for -300 volts DC
output, and connect divider tip to the output.
d. Set the gain adjustment of the Model 410B
(located at the rear of the instrument) for a reading
of exactly 3 volts.
e. Set the Voltmeter to the 30-volt range, and
measure the high voltage supply output at pin 8 of
transformer T401.

to 20 VOLTS/CM.
b. With POSITION controls, center a low intensity
spot on the CRT.
c. Alternately adjust FOCUS control and Astig-
matism adjustment R319, for the smallest, sharply
focused round spot.
5-69. INTENSITY LIMIT.
a. Center a defocused spot on the CRT,
b. Set INTENSITY control to "ten o'clock" position.
c. Adjust R307, Intensity Limit, to just extinguish
the spot.
5-70. GROUP II ADJUSTMENTS.
5-71. The procedures of Paragraphs 5-72 through
5-80 may be followed to calibrate either the vertical
or horizontal circuits. The Preliminary settings of
Paragraph 5-62 must be made first. Unless the pro-
cedure states otherwise, make only the setting or
connection for the circuit being calibrated, that is,
for either vertical or horizontal. The reference
designator for the vertical adjustment is given first,
followed by the corresponding horizontal adjustment,
e.g. R47/R238.
5-72. VERNIER BALANCE.
a. Set SENSITIVITY to 20 MV/CM.
b. Center spot with POSITION control.
c. Switch VERNIER out of CAL position.
d. Adjust R47/R238 for minimum shift of spot
when VERNIER is rotated.

d. Repeat steps b and c to obtain specified voltages.
e. This step applies only to the horizontal amplifier
adjustment and should be performed only when a more
accurate calibration is needed for use of the 10 USEC-
ONDS/CM, INTERNAL SWEEP X50 combination
setting. When more accurate calibration is desired
for this one sweep combination, make same settings
as in step a and proceed as follows:
(1) Connect a shorting wire between the green
and white wires (deflection plate leads) on the
horizontal amplifier circuit board.
(2) Clip the probe of a $ Model 428A/:B DC Milli-
ammeter around the black lead from the hori-
zontal POSITION control, R221B, to the ampli-
fier board.
(3) Adjust R276 for a Milliammeter reading of
15 ma.
(4) Disconnect Milliammeter and remove shorting
wire.
5-75. GAIN.
a. Connect the Voltmeter Calibrator to the amplifier
input terminals (shorting bar in place).
b. Set SENSITIVITY to 0.1 VOLTS/CM.
f. Alternately adjust C48/C240 and C49/C241 for
best rise time with no overshoot. Figure 5-3 illust-
rates the waveforms for the horizontal neutralization
adjustment.
A step input signal with a risetime much
faster than the Oscilloscope risetime, such
as the ,i Model 211A signal, may cause a
noticeable preshoot on the trace. This does
not affect the accuracy of the adjustment
and does not occur for signals within the
specified risetime of the Model 130C.
g. Disconnect shorting link from center input
terminal and connect Square Wave Generator be-
tween center and ground (black) terminals.
h. Connect a short jumper wire from the left
input terminal to the ground terminal.
i. Note the square wave response. A slight
rounding on the leading edge is permissible. If
desired, a compromise adjustment of C48/C240 and
C49/C241 can be made with Square Wave Generator
signal applied alternately to the left terminal (with
center terminal grounded) and to the center terminal
(with left terminal grounded).
c. Set output of Voltmeter Calibrator to 1 volt p-p. FREQUENCY COMPENSATION.
d. Set R69/R263, Gain, for exactly 10 c m deflection
on the CRT.
5-76. NEUTRALIZATION.
a. Connect the 75Q output of the Square Wave
Generator to the Model 130C amplifier input terminals
(connect between left terminal and center terminal
with grounding link in place).
b. For vertical neutralization adjustment, proceed
to step c (1). For horizontal neutralization adjustment
only, connect the Oscillator output to the Model 130C
vertical input and to the external sync input of the
Square Wave Generator; proceed to step c (2).
c. Make appropriate settings as follows:
(1) For vertical neutralization only, set

5-78. There are two methods for adjusting input
capacitance. One method requires a capacitance
meter or bridge and the other method requires an
alignment attenuator previously set (by L-C Meter
or capacitance bridge) for a specific value (see item
9 in Table 5-1). Paragraphs 5-79 and 5-80 provide
the procedures for these two methods.
5-79. PROCEDURE USING CAPACITANCE METER.
a. Set amplifier SENSITIVITY to 0.2 VOLTS/CM.
b. Disconnect the ground link from the center
terminal of the Model 130C amplifier input.
c. Connect the L-C Meter between the left (+ in-
put) and right (ground) terminals.
d. Adjust C21/C221, + Input Capacity, for a
reading of 45 pf on the L-C Meter.
Note
(2) For horizontal neutralization only set For Model 130C instruments with Option 06
Vertical SENSITIVITY - ? 5 VOLTS/CM (see Paragraph 1-9), change all references
Horizontal SENSITIVITY - - 0.2 VOLTS/CM in this procedure from "45 pf" to "85 pf".
d. Set Square Wave Generator frequency to 50 kc.
For horizontal neutralization, also set Oscillator
frequency to 25 kc.
e. Obtain CRT display as follows:
(1) For vertical adjustment only, set Square Wave
Generator output for about 8 cm. deflection.
(2) For horizontal adjustment only, set both signal
source amplitudes for about 8 centimeters
This is necessary because of input capaci-
tance added by the cabling to the rear panel
connectors.
e. Connect the L-C Meter between the center

square wave. Figure 5-4 illustrates the waveforms
for the horizontal compensation adjustment.
p. Set SENSITIVITY to 5 VOLTS/CM. Adjust
Square Wave Generator amplitude for about 8 cm
deflection.
q. Adjust C11/C215, 20V Atten. Comp, for best
square wave. Note that this adjustment is for the
5, 10, and 20 volt ranges.
r. Change Square Wave Generator signal lead to
the center terminal of the input. Connect a short
lead between the left and right terminals (lead still
connected from Oscilloscope ground terminal to
ground side of signal source).
s. Adjust C12/C216, 20V Atten. Comp, for best
square wave. Note that this adjustment is for 5, 10,
and 20 volt ranges.
t. Change SENSITIVITY to 2 VOLTS/CM. Adjust
Square Wave Generator output for about 8 cm
deflection.
u. Adjust C18/C218, 2V Atten. Comp, for best
square wave.
If using an L-C Meter for capacity adjustments,
disconnect the Square Wave Generator and
jumper wires. Refer to Table 5-9 and make
L-C Meter connections, SENSITIVITY settings,
and adjustments as specified.
(2) If using the alternate method of Paragraph 5-80,
retain the same instrument setup of step u in
Paragraph 5-79. Change the Square Wave Gen-
erator frequency to 1 kc. For the vertical
adjustment, change SWEEP TIME to 0.2
MILLISECONDS/CM, or for the horizontal
adjustment, change Oscillator frequency to
500 cps. Refer to Table 5-9 and connect the
square wave through the Alignment Attenuator
to the specified terminals (unused red input
terminal should always be connected to Oscil-
loscope ground). At each SENSITIVITY setting
adjust signal amplitude for about 8 cm deflection
and make the adjustment shown in the table.
