Response to
Query
Rx Reed-
Solomon
Interleaver Depth
RRD= 1 byte Command or Query.
Rx RS encoding, where:
0 = Interleaver Depth 4
1 = Interleaver Depth 8
2 = Interleaver Depth 16
Depending on Modem mode, overhead type, and data rate, not all
selections will be valid.
Example: RRD = 0 (This is a ‘don’t care’ if RS is Off under RRS)
RRD =
RRD?
RRD *
RRD #
RRD? RRD =x
(see Description
of Arguments)
Rx Reed-
Solomon
Decoding
RRS= 1 byte Command or Query.
Rx RS encoding, where:
0 = Off
1 = On
Depending on Modem mode, not all selections will be valid.
Example: RRS = 0 (RS encoding is Off)
RRS=
RRS?
RRS*
RRS#
RRS? RRS=x
(see Description
of Arguments)
Rx Spreading
Equation
RSE= 5 bytes Command or Query.
Rx Speading Equation, where:
a = Equation 0 or 1:
bbbb = GSN 0-9999
Example: RSE = 00000 (Rx Equation 0 GSN 0000)
RSE=
RSE?
RSE*
RSE#
RSE? RSE= abbbb
(see Description
of Arguments)
Rx Spreading
Factor
RSF= 4 bytes Command or Query.
Rx Spreading Factor, where xxxx is value from 1 to 512. Values other
than 1 are only valid when Modem Type = LDPC.
Example: RSF = 0001 (Rx Spreading Off)
RSF=
RSF?
RSF*
RSF#
RSF? RSF=xxxx
(see Description
of Arguments)
Rx Spectrum
Invert
RSI= 1 byte Command or Query.
Rx Spectrum Invert, where:
0 = Normal
1 = Rx Spectrum Invert
Example: RSI = 0 (selects Normal)
RSI=
RSI?
RSI*
RSI#
RSI? RSI=x
