6.2.4.5 Demodulator Alarms
(Common to all installed Burst Demodulators)
DEMODULATOR ALARM STATUS 1 THROUGH 4
DEMOD FPGA {Pass/Fail, Unmasked/Masked}
Indicates a receive FPGA hardware failure.
DECODER FPGA {Pass/Fail, Unmasked/Masked}
Indicates a decoder failure.
TUNER PLL {Pass/Fail, Unmasked/Masked}
Indicates that the Rx L-Band Synthesizer is not locked. This alarm will flash on
during certain gateway parameter changes. A solid indication points toward a
configuration problem within the gateway.
SIGNAL LOCK {Pass/Fail, Unmasked/Masked}
Indicates that the burst demodulator is unable to lock to a signal.
IFEC LOCK {Pass/Fail, Unmasked/Masked}
FRAME LOCK {Pass/Fail, Unmasked/Masked}
Indicates that the Framing Unit is unable to find the expected framing pattern.
ESNO Fault {Pass/Fail, Unmasked/Masked}
Indicates Rx signal quality fallen below input threshold.
CARRIER LEVEL {Pass/Fail, Unmasked/Masked}
Indicates Rx signal level has fallen below input threshold.
TESTPRN SYNC {Pass/Fail, Unmasked/Masked}
Indicates Rx pattern is synchronized to the data pattern
CLEAR LATCHED Allows the user to reset the latched alarms by selecting
