Response:
f']
This command causes all modem fault status to be returned. To
reduce the length of the response, fault status is embedded into
the bit structure of the characters that are returned. Faults are
indicated by a binary 1 in the designated bit position.
Where: Character 'a': Modulator fault status character 1.
Bit 6 = 1 always.
Bit 5 = Modulator module fault.
Bit 4 = RF output status actual, not programmed status (1 =
ON, 0 = OFF).
Bit 3 through Bit 0 = Binary representation (0 to 10) of the
number of modulator stored faults.
Where: Character 'b': Modulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = IF Synthesizer.
Bit 4 = Data Clock Activity.
Bit 3 = Data Clock Synthesizer.
Bit 2 = I Channel.
Bit 1 = Q Channel.
Bit 0 = AGC Level.
Where: Character 'c': Modulator fault status character 3.
Bit 6 = 1 always.
Bit 5 = Internal SCT Synthesizer.
Bit 4 = Programming.
Bit 3 = Configuration.
Bit 2 = External Reference Activity.
Bit 1 = reserved.
Bit 0 = reserved.
Where: Character 'd': Demodulator fault status character 1.
Bit 6 = 1 always.
Bit 5 = Demod module fault.
Bit 4 = Carrier detect status (0 for decoder lock).
Bit 3 through Bit 0 = Binary representation (0 to 10) of the
number of demodulator stored faults.
Where: Character 'e': Demodulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = IF Synthesizer Lock.
Bit 4 = Receive Clock Synthesizer.
Bit 3 = I Channel.
Bit 2 = Q Channel.
Bit 1 = Descrambler.
Bit 0 = BER threshold.
Where: Character 'f': Demodulator fault status character 3.
Bit 6 = 1 always.
Bit 5 = Programming.
Bit 4 = Configuration.
Bit 3 = reserved.
Bit 2 = reserved.
Bit 1 = reserved.
Bit 0 = reserved.
Where: Character 'g': Interface transmit side faults character 1.
Bit 6 = 1 always.
Bit 5 = reserved.
Bit 4 = reserved.
Bit 3 through Bit 0 = Binary representation (0 to 10) of the
number of interface transmit side stored faults.
Where: Character 'h': Interface transmit side faults character 2.
