Panasonic AJ-HPX3100G Setting External Reference Signal and GENLOCK, Locking video signal to external reference signal

Setting External Reference Signal and GENLOCK

Locking video signal to external reference signal

You can lock the video signals output from this unit to a reference signal provided externally.

This unit can receive external reference signals from the following two connectors.

zGENLOCK IN connector (for analog signals only)

zSDI IN connector (for SDI signals only)

GENLOCKing to standard signals provided from the GENLOCK IN connector

An HD-Y signal that matches system frame frequency or a composite signal is provided to the GENLOCK IN connector. To enable reference signals input to the GENLOCK IN connector, you need to select “GL IN” with the GENLOCK menu option. Select the output signal to lock the input reference signal with the GL PHASE menu option. (Only when 1080-59.94i, 1080-50i)

Perform horizontal phase adjustment of the reference signal and output signal with the H PHASE COARSE menu option and the H PHASE FINE menu option. You can select each menu option from the <GENLOCK> screen of the SYSTEM SETTING page.

‹Note

The sub-carrier of the composite signals of this unit is not locked to the sub-carrier of the reference signal.

GENLOCKing to standard signals provided from the SDI IN connector

Provides SDI signals matching system frame frequency to the SDI IN connector.

To enable reference signals input to the SDI IN connector, you need to select “SDI IN” with the GENLOCK menu option.

In addition, when “SDI” is selected with the REC SIGNAL menu option, the reference signal input to the SDI IN connector is synchronized regardless of the state selected with the GENLOCK menu option. The phase of the output signal at this time becomes the same as the reference signal provided to the SDI IN connector.

Perform horizontal phase adjustment of the reference signal and output signal with the H PHASE COARSE menu option and the H PHASE FINE menu option. You can select the REC SIGNAL menu option from the <SYSTEM MODE> screen of the SYSTEM SETTING page.

Recording for Settings and Adjustments
