How to adjust using the VCS-700
In the system with the MSU-700A/750, CNU-700/500 or
VCS-700, the video output signal of the unit can be
checked on the waveform or vector monitor connected to
the WF A OUTPUT connector and the WF B OUTPUT
connector of the VCS-700.
Connect the WF OUT connector of the DIF-124 board to
the WF 1 connector of the VCS-700 and connect the PIX
OUT connector to the PIX 1 connector. Then adjust the
signal level using the color bar signal.
1. Press the BARS button of the MSU-700A/750, RCP-
740/741, etc., or press the ENC button of the WAVE-
FORM MONITOR buttons (or MONITOR SELECT
buttons) to display the color bars on the waveform or
vector monitor.
2. Set the CONTROL switch of the VCS-700 to RESET.
3. Adjust the color bars signal using the WFM 1 LEVEL
and WFM 1 CHROMA controls of the VCS-700 so
that it is within the specified level.
Measurement point : PIX OUT connector on the VCS-
700
Specification : A = 100 ±1 IRE [for NTSC]
A = 700 ±7 mV p-p [for PAL]
(WFM 1 LEVEL control)
Each luminescent spot on the vector monitor must be
within the “4” range.

Waveform Monitor
The video output signal of the unit can be checked on the
waveform monitor connected to the WF OUT connector.
Adjust the WF output signal level using the color bar
signal.
In the system with the MSU-700A/750, CNU-700/500 or
VCS-700, the video output signal can be checked on the
waveform monitor connected to the VCS-700.

How to adjust on the RC-91 board of the unit
RC-91 board (A side)
1. Press the BARS button of the MSU-700A/750, RCP-
740/741, etc., or press the ENC button of the WAVE-
FORM MONITOR buttons (or MONITOR SELECT
buttons) to display the color bars on the waveform
monitor.
2. Adjust the color bar signal using control RV301
(WFM GAIN) and RV305 (WF CHROMA) on the
RC-91 board so that it is within the specified level.
