Description of Arguments
Command or Query.
Invert Transmit Data, where:
s=Defines which interface slot ( 1 or 2 )
x=Invert Transmit Data, where:
0=Normal
1=Inverted
Note: Command valid Only with HSSI
Example: TDI = 111 (Inverted TX Data selected)
Query only.
Composite Tx Data rate, in kbps, in the form xxxxxx.xxx.
Resolution=1 bps.
Example: TDR=002047.999 (2047.999 kbps indicated)
Command or Query.
Tx Frequency (in MHz) in the form xxxx.xxxx, where:
52 to 88 MHz, and 104 to 176 MHz (70/140 Modulator)
950 to 1950 MHz (L-Band Modulator)
Resolution=100Hz.
Example: TFQ=0950.0000
Command or Query.
Tx Frame Size Long/Short selection in the form x, where:
0=Short,
1=Long
Example: TFS =0 (Short Frame Size selected)
Note: Setting only valid in DVB-S2 mode.
Query only.
Tx FEC coding type in the form x, where:
0=Viterbi + Reed-Solomon
1=LDPC
FEC is dependent on the TX Mode Type.
Example: TFT=1 (LDPC coding indicated)
