Adjusting The Phases Of The Signals - Sony BVP-900 Series System Manual

3-3 Checking and Adjusting the Signal of the System
3-3-2 Adjusting the Phases of the
Signals
The signal phases between the units used in the BVP-
900-series video camera system must be adjusted so
that the phases are aligned. Before starting adjustment,
supply the following reference signals to each piece of
equipment, and turn the power of each unit ON.
CCU-700A/700AP/550A/550AP
A signal including a burst and sync signals
Signal level: 40 IRE (for CCU-700A/550) or 0.3 Vp-p
(for CCU-700AP/550P)
CNU-700/500
A signal including a sync signal
Signal level: 40 IRE (for the NTSC model) or 0.3 Vp-p
(for the PAL model)
Waveform monitor
A sync signal specified by the waveform monitor to be
used
Adjusting the phases of the sync signal of
the CCU-700A/700AP/550A/550AP
Adjust the phases of the output signals of all the CCU
used in the system so that the phases of the output
signals align the phase of the reference signal. You
can adjust the phase using the controls and switches on
the VA board of the CCU-700A/700AP/550A/550AP
and also with the Maintenance Menu of the MSU-
700A/750.
Adjusting on the VA board of the CCU-700A/700AP
Proceed as follows.
