qualifier)
Tx TCR= 1 byte, value of
1,3 or 7
FEC Code
Rate
Tx TMD= 1 byte, value of
Modulation 1 or 2 or 3
Type
Tx Spectrum TSI= 1 byte, value of
Invert 0 or 1
Description of arguments
(note that all arguments are ASCII numeric
codes, that is, ASCII codes between 48 and 57)
TFT?
If the Turbo Codec option is not installed, and the
argument 5 is used, the target will return TFT?
Use EID? to query the options fitted.
Command or Query.
Tx FEC Code rate, where:
1 = Rate 1/2
3 = Rate 3/4 (must be set for Rate 3/4 Turbo)
7 = Rate 7/8
8 = Rate 21/44 (must set for Rate 21/44 Turbo)*
9 = Rate 5/16 (must set for Rate 5/16 Turbo)*
All other codes invalid.
Example: TCR=1 (which is Rate 1/2)
* Only valid for S/W > 1.14 and EID =5500xx
As a Query, returns 0 if Uncoded is selected for
FEC
Command or Query.
Tx Modulation type, where:
1 = BPSK (must be set for Rate 21/44 or 5/16
Turbo)
2 = QPSK (must be set for Rate 3/4 Turbo
operation)
3 = OQPSK
All other codes invalid.
Example: TMD=2 (which is QPSK)
Command or Query.
Tx Spectrum Invert selection, where:
0 = Normal,
