Reference sources are flagged as 'valid' when
active, 'in-band' and have no phase alarm set.
All sources are continuously checked for
activity and frequency.
Only the main source is checked for phase.
A phase lock alarm is only raised on a
reference when that reference has lost phase
whilst being used as the main reference. The
micro-processor can reset the phase lock
alarm.
A source is considered to have phase locked
when it has been continuously in phase lock
for between 1 and 2 seconds
