The three 2-axis systems will be identical to the previous
2-axis system for the reading head. On both
the 2-axis systems already delivered, there has been some
mismatch with respect to 0 input impedance. has been

On the new counters now in work would like to avoid any STAT
input impedance mismatch. has discussed this STAT
in detail with telephone and has received verbal
direction from o n. however, would like written
clarification of the input impedance requirements. He needs
this no later than 1 August 1964. The clarification II STAT
wants is:
1. Define the input pulse (which is the pulse that
defines a count). This is the pulse from the
sensor to the F---] input amplifier.
a. Min/max voltage level for a 0.
