Arguments
Description of Arguments
or Response
to Query
Tx FEC coding type, where:
0=Viterbi + Reed-Solomon
1=LDPC
( FEC is dependent on the TX Mode Type. )
Example: TFT=1 (which is LDPC coding)
Interface Slot Enable/Disable, where:
s=Defines which interface slot (1 or 2)
x=Tx Interface Status, where:
0=Disabled
1=Enabled
Ex: TIE =11 (Enables transmit interface)
Tx Alpha Rolloff, where:
0 = 20%
1 = 25%
2 = 35%
Example: TAR=0 (which is a Tx Alpha Rolloff of 20%)
Tx Gold Code Sequence Index:
xxxxxx = Gold Code Sequence index ( 0 to 262141 )
Example: TGS=189063
*NOTE: Only valid in DVB-S2 mode.
