(see description of
arguments)
Tx FEC Type TFT= 1 byte, value
of 0 thru 6 Command or Query.
Tx FEC coding type, where:
0=None (uncoded - no FEC) (Forces TCR=7 1/1) with
differential encoding ON
1=Viterbi
2=Viterbi + Reed-Solomon
3=Reserved – do not use
4= Reserved – do not use
5=TCM + Reed-Solomon (Forces TCR=3 2/3)
6=Turbo
7= TPC/LDPC (Future option)
Example: TFT=1 (which is Viterbi coding) TFT=
TFT?

TFT#
TFT+ TFT? TFT=x
(see description of
arguments)
Tx
Modulation
Type TMD= 1 byte, value
of 0 thru 5 Command or Query.
Tx Modulation type, where:
0=BPSK
1=QPSK
2=OQPSK
3=8PSK
4=16-QAM (Turbo or Viterbi + RS only)
5=8-QAM (Future option)
Depending on FEC type, not all of these selections will be valid.
Example: TMD=2 (which is OQPSK) TMD=
TMD?
TMD*
TMD#
TMD+ TMD? TMD=x
