Reference Change: SecureSync has switched from one input reference to
another (for example, IRIG was the selected input being used, but now
GNSS is the selected reference).
GPS Antenna Problem: The GPS Antenna Problem alarm indicates the
GNSS receiver has detected an over-current or undercurrent condition (an
open or short exists in the GNSS antenna cable, or the GNSS antenna is not
connected to SecureSync). The receiver will attempt to continue the nor-
mal acquisition and tracking process regardless of the antenna status. The
current draw measurements that will indicate an antenna problem are:
Under-current indication < 8 mA
Over-current indication > 80 mA
Note: This alarm condition will also be present if a GNSS antenna
splitter that does not contain a load to simulate an antenna being
present is being used.
GPS Antenna OK: The antenna coax cable was just connected or an open
or short in the antenna cable was being detected but is no longer being
detected.
Frequency Error: The oscillator's frequency was measured and the fre-
quency error was too large. Or, the frequency couldn't be measured
because a valid input reference was not available.
Frequency Error cleared: The Frequency Error alarm was asserted but was
then cleared.
In Holdover: Input references were available, but all input references have
since been lost. If the references are not restored before the Holdover
period expires, time sync will be lost.
No longer in Holdover: Input references were lost at one point (or
declared not valid), but have since been restored OR the Input references
