Status Faults
Command:
Response:
BCSF_abcdefghijkl'cr''lf']
This command causes all modem fault status information 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.
Character b: Modulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = IF Synthesizer.
Bit 4 = Data Clock Synthesizer.
Bit 3 = reserved.
Bit 2 = reserved.
Bit 1 = AGC Level.
Bit 0 = reserved.
Note: In TX Burst mode only.
Character b: Modulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = IF Synthesizer.
Bit 4 = Data Clock Synthesizer.
Bit 3 = I Channel.
Bit 2 = Q Channel.
Bit 1 = AGC Level.
Bit 0 = reserved.
Note: In TX Continuous mode only.
Character c: Modulator fault status character 3.
Bit 6 = 1 always.
Bit 5 = reserved.
Bit 4 = reserved.
Bit 3 = reserved.
Bit 2 = reserved.
Bit 1 = reserved.
Bit 0 = reserved.
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.
Note: In RX Continuous mode only.
Character e: Demodulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = IF Synthesizer Lock.
Bit 4 = I Channel.
Bit 3 = Q Channel.
Bit 2 = Descrambler.
Bit 1 = BER threshold.
Bit 0 = reserved.
Note: In RX Continuous mode only.
