Description of Arguments
Command or Query.
Rx Differential Decoding in the form x, where:
0=Off
1=On
Depending on FEC type or Modulation Type, not all selections will be valid.
Example: RDD=1 (selects Rx Differential Decoding On)
Command or Query.
Receive Data Fault, where:
0=None
1=DATA
2=AIS
Example: RDF=0 (selects Data Fault = None)
Command or Query.
Invert Receive Data, where:
0=Normal
1=Inverted
Example: RDI=1 (selects Inverted RX Data)
Command or Query.
Rx Scrambler state, where:
0 = Off
1 = OM-73 Scrambler
2 = IESS-V.35 Scrambler
3 = Modified V.35 (Comtech EF Data Closed Network)
4 = Reed-Solomon Synchronous Scrambler
5 = IBS Overhead Synchronous Scrambler
6 = TURBO Scrambler
Depending on Modem mode, FEC type, overhead type, and RS state, not all selections
will be valid.
Example: RDS=1 (OM-73 Scrambler On)
Query only.
Unit returns the value of the measured frequency offset of the carrier being demodulated.
Values range from ± 0 to ± 30 kHz, 100 Hz resolution.
Returns 99999 if the demodulator is unlocked.
Example: RFO=+02.3 (selects + 2.3 kHz)
Command or Query.
Rx Frequency, 52 to 88 MHz, 104 to 176 MHz, and 950 to 2000 MHz.
Resolution = 1000Hz.
Example: RFQ=0140.987
