Response to Query
Live Tx Faults N/A 8 bytes Query only.
Live Tx Faults are returned as a 32 bit Hexadecimal value. Bit
values are defined as follows:
80000000 = Modulator Symbol Clock not locked
40000000 = Modulator RF Synthesizer not locked
20000000 = Modulator No IQ Activity
10000000 = Modulator Nyquist Filter Clipping
08000000 = Interface data clock PLLs not locked
04000000 = Interface Terrestrial Clock No Activity
02000000 = Interface SCT PLL not locked
01000000 = Interface No Data Activity
Example: TXF=00000000 indicates No Tx Faults
N/A TXF? TXF=xxxxxxxx (see
description of
arguments)
Live Rx Faults N/A 8 bytes 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 Fault
02000000 = Interface Buffer about to slip
01000000 = Interface Buffer has overflowed
00800000 = Interface Buffer has underflowed
00400000 = Interface Buffer Clock PLL not locked
00200000 = Interface Buffer Clock Reference Activity
00100000 = Interface Data/AIS
00080000 = Eb/No Threshold exceeded
Example: RXF=00000000 indicates No Rx Faults
N/A RXF? RXF=xxxxxxxx (see
description of
arguments)
