•

– select one of the radio buttons to enable the Genlock
submodule or allow the reference to freerun.
•
Input Standard Selection

for the reference input. Refer to
•
Loop Bandwidth
– set this control for either fast locking (
Fast Lock
) to the
reference or for the lowest jitter performance (
Low Jitter
) depending on
the stability of the reference signal being used.
For example, if Low Jitter is selected and the Status is still
Invalid

one minute has passed, the input reference has excessive wander that
cannot be tracked in Low Jitter mode. Switch to
Fast Lock
and verify
Status is
Locked
after about 10 seconds.
