types.
Change the module.
Warnings
Message Meaning Solution
10MHZ
OSC.TEMPERATURE
WRONG The temperature of the 10
MHz oscillator of the
module FAB is wrong. The thermostat may be
faulty
Change the sub-assy of the
frequency processing.
10 MHZ OSC. TUNING
NEAR LIMIT Tuning voltage of the 10
MHz oscillator is near the
limit. Change the sub-assy 10
MHz oscillator in the
module FAB.
1 PPS OF INTERNAL GPS
MISSING The 1 PPS signal is absent. Check the GPS reception.
