Genlock
This function allows various modes of genlock to
be enabled.
Genlock
Genlock Enable
When selected the unit will lock to an incoming
reference signal.
When not selected the output signal will be
free-running.
In this mode the frequency accuracy will be
±10 ppm.
Genlock Offset SECAM NTSC443 (ns Scroll Bar)
These items allow adjustment of the horizontal
timing of the output signal relative to the reference
sync signal, in nanoseconds.
The range is ±1.9 lines in steps of one cycle of
subcarrier.
Genlock Offset Phase PAL (ns Scroll Bar)
(also PALN/NTSC/PALM)
These items allow adjustment of the horizontal
timing of the output signal relative to the reference
sync signal, in nanoseconds.
The range is ±1.9 lines in steps of one cycle of
subcarrier (this ensures the correct SC/H timing is
maintained).
Selecting Preset returns the setting to zero (output
coincident with reference).
Genlock Offset Phase PAL (Deg Scroll Bar)
(also PALN/NTSC/PALM)
This function allows the relative phasing between
the reference subcarrier and the output signal
subcarrier to be adjusted.
The range of adjustment is 359.9° (continuously
adjustable) in steps of 0.1°. The preset value is 0°
(output coincident with reference).
