This letter, together with attachments, constitutes
our proposal for increased scope involving Phase B and E of
T.O. 7 of Contract RD-79. The estimated cost, price and fixed
fee are an follows:
Phase B
Phase E
Estimated Cot
Fined Fee
Estimated Price
56,48 25X1
5,805.00
It is requested that the contract date be extended to
December 15, 1957 to permit completion of the proposed work.
This date is predicated upon receiving transistor amplifiers
from the client on or prior to October 1, 1957, and additional
GFE equipment as follows:
Hewlett-Packard Generators Model 608C
612A
In the event during system tests, y stem 4y+etee will not
operate due to cables built to client's specifications or to
GFE operation, contractor cannot assume responsibility for
repair of these items. If the design is fundamentally wrong,
contractor will attempt to ascertain the correction or change
required and will furnish this information to the client
Yours very truly,
Bpi

CMGE IN SCOPE M PHASE B OF
s 957
The increased scope of the work under Phase B consists
?
of two general areas of effort:
1.
Determination of Filter-Detector Combination
?
Bandpass Characteristics,
2.
Amplification of System Tests
0
0
In the course of development and production of the CS-3,
and CS-3A systems, changes were made in requirements necessi-
tating changes in-the systems. It now seems desirable to
furnish a more thorough system test than originally antici-
pated.
1. Determination of Filter-Detector Combination Band-
Pass Characteristics for Bands A, B, C. and D.
Under Task Order 5, per-
formed measurements on filter-detector band-
pass characteristics. On the basis of results,
it was decided to use bias on the detector.
With bias the bandpass characteristic will be
different, and new measurements will be required.

One filter for each band will be measured in
combination with one crystal detector. Ten
frequencies per band will be measured. The
data will be submitted in graph form. In
addition, two filters will be spot checked
with two different crystal detectors.
2. Amplification of System Tests
The CS-3A system will be set up in the
laboratory utilizing cables constructed for
the system at their maximum length. The tests
to be performed will be comprehensive com-
pared to those called for under the original
scope of Phase B.
Signal inputs will be applied directly
to the filters for bands A, B, C, and 0,
using GFE signal generators listed in the
attached letter. For band E, the generator
will feed the detector assembly as no filter
exists. Sensitivity measurements will be made
to determine 10% and 100% recording level
requirements (recording level voltages to be
furnished by the client).

Two filters of each type, with each of two
different detector assemblies will be measured
at three frequencies per band (10% above low
frequency cut off, center frequency, and 10%
below high frequency cutoff). For band E,
measurements will be made as above with two
detector assemblies feeding the generator
directly into the detector. One filter detec-
tor combination will be checked at low, cen-
ter, and high DC power voltage.
Tests will be made to determine if, in
conjunction with the system, the VA-5 amplifier
performs to its specifications. For this test,
between six and ten amplifiers will be inves-
tigated to assure results based on sufficient
sampling.
The system will be tried with at least
two recorders, two different power supplies,
and two activity amplifiers. A suitable way
of performing this will be to freeze all var-
iables, replace the equipment, then check to
see if there is a variation in operation.

all
The complete system test will be made
using half of a dual rack assembly. Con-
tractor feels that no interference problems
will arise when the other half of the rack
is placed into operation.
In general, all tests will be made with
a 2 usec pulse at 1000 cps, generators per-
mitting. Spot checks will be made at rates
of 30 cps. and 6000cps.
The CS-3 system is identical to the
CS-3A except in cabling and in the number
of power supplies. The use of two supplies
versus one should not affect sensitivity
results. For this reason, the complete tests
will not be run on the CS-3 system. The sys-
tem will be set up and spot measurements made
to determine if the system operates the same
as the CS-3A system.
The Test Bench Junction Box System will
be tested in the same manner as the CS-3 Sys-
tem.

ing block diagrams and schematics for the systems, and to pre-
pare information for the installation and test of the systems.
Changes in the system during the design and manufacturing.
stages have made obsolete many of the drawings and information
prepared by the client. In addition, information is lacking
on the actual installation of the operating systems and on
the use of the Test Bench Junction Box System.
It is also proposed that check
existing client drawings to insure that they includ* changes
made in the system after preparation of the drawings.

The preparation of the installation manual will be pat-
terned after the attached outline. Extensive use will be made
of drawings and photographs to enable the user to most expedi-
tiously install and test the equipment.
The section of the manual on the installation of the
? CS-3A system will be more comprehensive than the section on
? the CS-3 system. There are only a few basic differences
between the systems and for this reasons, much of the infor-
mation on the CS-3A will be applicable to the CS-3 system.
A section will be included showing the interconnection
of the Test Bench Junction Box System. An explanation of the
capabilities of the Test Bench Junction Box and its instru-
mentation will be given.
