Adjusting the VCS-700
No phase adjustment is required.
Note
The VCS-700 is synchronized with the sync signal of
the signals input to the PIX 1 through 6 connectors on
the rear of the VCS-700. If the input signal does not
have a sync signal, control signals such as a staircase
signal for a waveform monitor may not work correctly.
Adjusting the phase on the ARU-701
Adjust the output signal of the ARU-701 so that the
phase aligns with that of the reference signal. Perform
the adjustment using the controls on the front panel of
the internal board. Proceed as follows.
