Adjustment Standard Adjusting Point
Step 1
• Input the 0 to 40 MHz sweep signal The 0 to 30 MHz range of the TP2 (R) output 1 CV100 (B-2) BK board
with the RGB signal input. waveform is flat : If outside the standard:
(MARKER ON) 1 RV100 (B-2) BK board
• Rotate RV100 fully in the clockwise
direction (2).
• Connect an oscilloscope to TP2 (R)
of the C board using a 100:1 FET
probe.
• Adjust CV100 so that the waveform
satisfies the standard.
If unadjustablecompletely using
CV100, adjust to satisfy the standard
while tracking with RV100 and CV100.
Note: Adjust so that the 25 MHz marker becomes 0
dB, and check if the above standard is satis-
fied.
