Hi,
I can't be 100% sure, but my understanding is it
just compares to its internal
OCXO.
It know the margin of error of its OCXO, so if the incoming freq is more
different than what it expects, Either the OCXO went bad or the incoming
clock is bad. In either case, it's a fault.
OK, possibly less sophisticated than expected :) I have thought about some crazy jitter
and drift detection...
Cheers,
Sylvain
Thanks!
