Response to Query

Tx Frequency

TFQ=

9 bytes

Command or Query.
Tx Frequency
CDM-570L: 950 to 1950 MHz
CDM-570: 50 to 90 and 100 - 180 MHz
Resolution=100 Hz
Example: TFQ=0950.9872
Example: TFQ=0073.4528

TFQ=
TFQ?
TFQ*
TFQ#

TFQ?

TFQ=xxxx.xxxx
(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?

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
