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.
GENLOCK IN connector (for analog signals only)
SDI 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.
The following output states result from selection of external reference signals and GENLOCK setting.

Adjustments and Settings for Recording Setting External Reference Signal and GENLOCK
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.
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.
State of output signal
(phase relation with external reference signal)
HD SDI output matches HD SDI input signal.
For the HD SDI input signal, the VBS output delays by about 90 H.
VBS output matches HD SDI input signal.
For the HD SDI input signal, the HD SDI output gains by about 90 H.
HD SDI output is non-synchronous with HD SDI input signal.
VBS output is non-synchronous with HD SDI input signal.
HD SDI output matches HD-Y input signal.
For the HD-Y input signal, the VBS output delays by about 90 H.
VBS output matches HD-Y input signal.
For the HD-Y input signal, the HD SDI output gains by about 90 H.
HD SDI output matches VBS input signal.
For the VBS input signal, the VBS output delays by about 90 H.
VBS output matches VBS input signal.
For the VBS input signal, the HD SDI output gains by about 90 H.
