Genlock
Genlock
When enabled the unit will lock to an incoming
valid reference signal with parameters set using
this screen. When not enabled the output signal
will be free-running. In this mode the frequency
accuracy will be ±10 ppm.
Mode
Two modes of locking to the reference signal may
be selected.
SCH
The unit will lock to the Line, Field and
subcarrier signals of the reference signal.
HV
The unit will only lock to the Line and
Field signals of the reference signal.
Note that the
Genlock SC Phase
controls may be adjusted but the settings
will be irrelevant in this mode.
Genlock Offset Phase PAL
This item allows adjustment of the horizontal timing
of the output signal relative to the reference sync
signal, in nanoseconds.
The range is approximately ±113
µs in steps of
one cycle of subcarrier (225 ns). (This ensures the
correct SC/H timing is maintained)
Selecting Preset returns the setting to zero.
(Output coincident with reference)
Genlock Offset Phase PALN
This item allows adjustment of the horizontal timing
of the output signal relative to the reference sync
signal, in nanoseconds.
The range is approximately ±113
µs in steps of
one cycle of subcarrier (279 ns). (This ensures the
correct SC/H timing is maintained)
Selecting Preset returns the setting to zero.
