n
The GPS satellite signals may be blocked from reaching the antenna, or are too weak to
be detected by the receiver.
n
The GPS antenna cable may be disconnected, broken, shorted, or too long.
Timing Timecode Source Alarm: The Hardware Clock is not detecting a valid input signal on the
IRIG In connector.
Timing PPS Source Alarm: The Hardware Clock is not detecting a valid input signal on the
1PPS In connector.
Timing 10MHz Source Alarm: The Hardware Clock is not detecting a valid input signal on the
10MHz In connector.
Timing GPS Antenna Short Alarm: (Displayed on GPS-equipped SyncServers only) The GPS
receiver detects an overcurrent condition on the GPS antenna cable. The likely cause is a
short circuit.
Timing GPS Antenna Open Alarm: (Displayed on GPS-equipped SyncServers only) The GPS
receiver detects too little current in the power supplied to the GPS antenna. The likely cause
is a disconnected or broken GPS antenna cable. A GPS splitter may also cause this con-
dition.
Timing Oscillator DAC Range Alarm : The SyncServer is applying the maximum or minimum
DAC value to steer the oscillator. If this recurs frequently or over a sustained period of time,
there may be a problem with the oscillator.
Timing Rubidium Lock Alarm: The optional Rubidium oscillator, if installed, has not stabilized its
frequency output. After power up, this alarm may be raised for up to several minutes until the
Rubidium warms up and stabilizes its frequency output.
Timing Oscillator Unlock Alarm: The Hardware Clock's oscillator frequency is not locked to the
reference source.
Timing Source Change: The Hardware Clock has switched timing references.
Timing Source Change Lower Accuracy Input: The Hardware Clock has switched to a lower-pri-
ority timing source.
Timing PLL Unlock Alarm: The Hardware Clock oscillator's PLL unlocked.
Timing Time Quality 1e-6 Alarm: The Hardware Clock's estimated time error has exceeded 1e-
6 seconds (1 microsecond).
Timing Time Quality 1e-5 Alarm: The Hardware Clock's estimated time error has exceeded 1e-
5 seconds (10 microseconds).
Timing Time Quality 1e-4 Alarm: The Hardware Clock's estimated time error has exceeded 1e-
4 seconds (100 microseconds).
Timing Time Quality 1e-3 Alarm: The Hardware Clock's estimated time error has exceeded 1e-
3 seconds (1 millisecond).
Timing Leap Event Alarm: The leap indicator from the Hardware Clock's GPS or IRIG 1344 tim-
ing references, indicates that a leap event is pending. The pending event can be a Leap
Second Insertion, Leap Second Deletion, or Clear Alarm, which indicates that the alarm has
passed. See STATUS - Timing for more information.
