SPEC.
A=11+/-1nS (Phase Pre-Setting )
B=10+/-1nS
1. Adjust VR1 so that the Pulse width B at TP1
(SMPL) on the PERAMP Board is 10+/-1nS.
2. Adjust VR3 so that the Phase difference A
between TP1 and TP5 is 11+/-1nS.
NOTE
The observation of the phase below based on the DC
2.5V level.

SPEC.
A=18+/-1nS (Phase Pre-Setting )
B=19+/-1nS
1. Adjust VR2 so that the Pulse width B at TP2
(CLMP) on the PERAMP Board is 19+/-1nS.
2. Adjust VR4 so that the Phase difference A
between TP2 and TP5 is 18+/-1nS.
3. Aim the Grayscale chart and connect a scope to
TP102, TP202 and TP302 on the PRE AMP
board.
4. Confirm that the waveform shape as follows when
the IRIS is changed from CLOSE to OPEN. If
waveform is NG condition, adjust VR4 so that the
signal Level at each TP in the figure is minimized.
