The HCO-3901 output signals should always be genlocked
to some reference source. The genlock source is selected in
the Reference control panel. Use the radio buttons in the
Reference Source area to select from the following options:
•
Auto – this mode selects the first source detected in this
order of priority:
o

o
URS
o
Selected Input signal
•
External – selects the signal connected to the rear-panel
REF IN connector
•
URS (Universal Reference Signal) – selects the internal
reference from the backplane
•
Input – uses the currently-selected input signal.
URS Format – use the radio buttons in the URS Format area
to select whether the URS is OFF, 29.97 Hz or 25 Hz.
The genlock is used to assure a switch during the vertical
interval of the genlock source.
See the Timing panel (section 3.4.4) for a display of the
measured timing between the outputs and the reference,
and to set the output timing.
