Parameter
Type
Command
(Instruction
Code and
qualifier)
Arguments for
Command or
Response to
Query
Description of arguments
(note that all arguments are ASCII numeric
codes, that is, ASCII codes between 48 and 57)
Response to Command
(target to controller)
Query
(Instruction
Code and
qualifier)
Response to
query
(target to
controller)
Tx
Frequency
TFQ= 8 bytes 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
TFQ= (message ok)
TFQ? (received ok,
but invalid arguments found)
TFQ* (message ok, but not
permitted in current mode)
TFQ? TFQ=xxx.xxxx
(same format as
command
arguments)
Tx
Data Rate
TDR= 8 bytes 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)
TDR= (message ok)
TDR? (received ok,
but invalid arguments found)
TFQ* (message ok, but not
permitted in current mode)
TDR? TDR=xxxx.xxx
(same format as
command
arguments)
Tx
FEC Type
TFT= 1 byte, value of
1,2,3 or 4
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 ar
g
ument 3 or 4 is used
,
the tar
g
et will return
TFT= (message ok)
TFT? (received ok,
but invalid argument found)
TFT* (message ok, but not
permitted in current mode)
TFT? TFT=x
(same format as
command
arguments)
