Testing the GPS Master Clock
If you use a satellite GPS master clock for time synchronization, you can check
presence and time quality of the acquired IRIG-B signal. Type irig and press
Enter.
>irig
Testing IRIG-B time code signal. To stop test, press any key.
IRIG-B: received: 24, time quality: 9, edge faults: 0, pulse
faults: 2.
If the IRIG-B signal is present on the SA300 IRIG-B connector, the number of
received frames is updated each second.
The fault counters normally show small numbers recorded until the SA300 has
acquired the time code and synchronized to the IRIG-B signal.
The time quality is represented by a number from 0 to 15. The time quality is 0 if the
time is locked, and 8 and more if the GPS receiver has lost the satellite reference
time and is running in freewheeling mode.
To exit the test, press Enter.
