Loop Bandwidth
– set this control for either fast locking (
Fast Lock

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

Fast Lock
and verify

Locked
after about 10 seconds.
