Frankly, I see no need for a lab standard to make any attempt to keep
"good" time when the GPS or the OCXO is compromised. Detect the
error, set an alarm, and disable the standard frequency output. Who
wants to do time-nut experiments with a standard that is limping
along with compromised accuracy?
It's perfectly fine if the standard automatically returns to normal
operation when it can (in this case, it should maintain a record of
the outage(s)), but it is also perfectly fine (IMO) to require manual
intervention to resume normal operation.
Again -- Who wants to do time-nut experiments with a standard that is
limping along with compromised accuracy?
It is a different situation if the standard provides timing for a
real-time application, such as a cell site. In that case, one
probably wants to maintain operation as long as the standard can be
relied on to meet the minimum system spec.
