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 Spreading Equation, where:
a = Equation 0 or 1:
bbbb = GSN 0-9999(eq=0) or GSN 0-4095(eq=1)
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
(see Description of
Arguments)
Rx Signal
Level
N/A 5 bytes Query only.
Unit returns the value of the Rx signal level in the form sxx.x, where:
s = + (positive) or – (negative) sign
xx.x – Rx signal level value in dBm, b15.0 and –60.0 dBm
Examples:
RSL = +99.9 (RSL > +15.0 dBm)
RSL = +15.0
RSL = -60.0
RSL = -99.9 (RSL < -60.0 dBm)
N/A RSL? RSL=sxx.x
