Description
The start of the first pulse of the inverted sync signal
to occur at 27.7 to 28.1 microseconds in relation to the
programmable digitizer trigger.
The first pulse of the noninverted sync signal for 3.7 to
3.9 microseconds.
The second pulse of the noninverted sync signal for 3.7 to
3.9 microseconds.
The third pulse of the noninverted sync signal for 3.7 to
3.9 microseconds.
The time interval between the first and second pulses of
noninverted sync signal for 37.6 to 38.6 microseconds.
The time interval between the end of the second pulse and
start of the third pulse of the noninverted sync signal
for 0.9 to 1.1 microseconds.
The start of the first pulse of the noninverted sync
signal to occur at 27.7 to 28.1 microseconds in relation
to the programmable digitizer trigger.
To check the camera video signal, the camera video output is pro-
grammed for windows of +2.00
vdc with a duration of 15 micro-
seconds occurring on lines 100 and 101 at 15 microseconds after
the start of the horizontal sync.
The programmable digitizer
assembly is triggered 10 microseconds into line 99, and the fol-
lowing checks are made:
The width of the first window for 14.8 to 15.2 micro-
seconds.
The width of the second window for 14.8 to 15.2 micro-
seconds.

The
first window to occur 42.4 to 43.5 microseconds after
programmable digitizer trigger.
second window to occur 80.5 to 81.6 microseconds after
programmable digitizer trigger. Line 102 for no cam-
window.
camera video amplitude for +1.4 to +1.9 vdc.
