Optical Test Target
line (indicating vertical reference); a
zero azimuthal reference line; 2 de-
grees (from vertical) subtense lines
(image tilt limits); a pair of near verti-
cal lines, the separation of which sub-
tends 2 degrees in azimuth at the
receiver-transmitter (image wander
limits): 1O degrees azimuth (vertical)
lines; and -10 degrees, +20 degrees
elevation (horizontal) lines.

4.6.1.1 Initial conditions.  Unless otherwise specified herein,
connect the loads, auxiliary equipment, power, and input signals to the unit
as specified in table I prior to performing the tests specified herein.
4.6.1.2 PFN voltage adjustment.  Prior to performing the tests of
4.6.4. initially adjust R10 of the PFN Charge power supply (10559345) for
the PFN voltage determined by test and recorded for the transmitter
component assembly (10559479), in accordance with MIL-C-14880.
Radjust the PFN voltage for a laser energy output of 50 5 millijoules.
4.6.1.3 Laser firing Procedure. LAser firing is accomplished
by applying a momentary logical zero type_A signal to -J (Manual
Reset) followed by a momentary closing of the RANGE switch shown on
figure 1.
