Adjusting the Sync and Subcarrier Phases of theVideo Signals
When you adjust the phases of the video signals,
follow the steps below.

Performing a phase adjustment operation

1Press the SCH button on the vectorscope.
The vectorscope goes into the SCH mode.
2Press the B channel button on the vectorscope.
