Response to Query
Tx Data Fault TDF= 1 byte, value of 0
thru 2
Command or Query.
Transmit Data Fault, where:
0=None
1=DATA
2=AIS
Example: TDF=0 (selects Data Fault = None)
TDF =
TDF?
TDF*
TDF#
TDF? TDF=x
(see Description
of Arguments)
Tx Data Invert TDI= 1 byte, value of 0
or 1
Command or Query.
Invert Transmit Data, where:
0=Normal
1=Inverted
Example: TDI=1 (selects Inverted TX Data)
TDI =
TDI?
TDI*
TDI#
TDI? TDI=x
(see Description
of Arguments)
Tx Frequency TFQ= 9 bytes Command or Query.
Tx Frequency, 52 to 88 MHz, 104 to 176 MHz, and 950 to 2000 MHz
Resolution = 100Hz.
Example: TFQ=0140.9872 TFQ=
TFQ?
TFQ*
TFQ#
TFQ? TFQ=xxxx.xxxx
(see Description
of Arguments)
Tx Power Level TPL= 5 bytes Command or Query.
Tx Output power level, where:
s=sign ( + / - )
xx.x = Tx Output power level, +10.0 and –40.0 dBm.
Example: TPL=-13.4
TPL=
TPL?
TPL*
TPL#
TPL? TPL=sxx.x
(see Description
of Arguments)
Tx
Reed-Solomon
Interleaver
Depth
TRD= 1 byte, value of 0
to 2
Command or Query.
Tx 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: TRD=0 (This is a ‘don’t care’ if RS is Off under TRS)
TRD =
TRD?
TRD *
TRD #
TRD? TRD =x

Encoding
TRS= 1 byte, value of 0
or 1
Command or Query.
Tx RS encoding, where:
0=Off
1=On
Depending on Modem mode, not all selections will be valid.
Example: TRS=0 (RS encoding is Off)
TRS=
TRS?
TRS*
