qualifier)
Tx TFQ= 8 bytes
Frequency
Tx TDR= 8 bytes
Data Rate
Tx TFT= 1 byte, value of
1,2,3 or 4
FEC Type
Description of arguments
(note that all arguments are ASCII numeric
codes, that is, ASCII codes between 48 and 57)
Command or Query.
Tx Frequency, 52 MHz to 88 MHz, (70 MHz band)
or 104 MHz to 176 MHz, (140 MHz band).
Resolution = 100Hz.
Example: TFQ=072.9876 (70 MHz option)
TFQ=148.0000 (140 MHz option)
Note: Querying 'Options Fitted' (using EID?) will
indicate if the unit is 70 MHz or 140 MHz IF band
Command or Query.
Tx Data rate, in kbps, between 2.4 kbps and 2048
kbps. Resolution = 1 bps.
Example: TDR=2047.999 (which is 2047.999 kbps)
Command or Query.
Tx FEC coding type, where:
0 = None (uncoded - no FEC)
1 = Viterbi
2 = Sequential
3 = Viterbi + Reed-Solomon
4 = Sequential + Reed-Solomon
5 = Rate 3/4 QPSK Turbo (S/W Version < 1.15)
6 = Rate 21/44 BPSK Turbo (S/W Version > 1.14)
7 = Rate 5/16 BPSK Turbo (S/W Version > 1.14)
All other codes invalid.
Example: TFT=1 (which is Viterbi coding)
Note: If the RS Codec option is not installed, and
the argument 3 or 4 is used, the target will return
61
