Rx acquisition sweep range of demodulator, in kHz, ranging from 0 to 60 kHz.
Example: RSW=0060.000 (selects 60 kHz)
Query only.
Live Rx Faults are returned as a 32 bit Hexadecimal value. Bit values are defined as
follows:
80000000 = Demodulator IF not locked
40000000 = Demodulator Data Decoder not locked
20000000 = Demodulator RF Synthesizer not locked
10000000 = Demodulator No IQ Activity
08000000 = Interface De-Multiplexers not locked
04000000 = Interface Buffer Clock PLL not locked
02000000 = Interface Data/AIS
01000000 = Eb/No Threshold exceeded
00800000 = Composite Power > 20 dBm
00400000 = Composite Power > 40 dBc
00200000 = BERT Sync Loss
00100000 = LNB Voltage out of range
00080000 = LNB Current out of range
Example: RXF=00000000 indicates No Rx Faults
