3-2 Reference Sync Signals

This section describes how reference signals for the video output signals and servo system are selected.

The output from the internal reference video signal generator is supplied to the output video signal and servo circuits as a reference signal.

3-2-1 Selecting Reference Sync Signal Depending on Operational Status

The reference sync signal selection switches automatically between REF and INPUT depending on the menu settings and the operating status of the unit, as shown in the following table.

Notes

•When there is no HDSDI signal input whereas INPUT is selected, the unit synchronizes with the REF signal.

•When there is no REF signal input whereas REF is selected, no external reference signal is used. In this case, the unit synchronizes with the internally generated reference signal.

3-2-2 Connecting Reference Signals

Connect reference signals as shown below, according to the way in which the unit is to be used.
