Description of Arguments
Command or Query.
Rx Frequency (in MHz) in the form xxxx.xxxx:
52 to 88 MHz, and 104 to 176 MHz (70/140 Modulator)

Resolution=100Hz.
Example: RFQ=0950.0000
Query only.
Rx Frame Size Long/Short selection in the form x, where:
0=Short,
1=Long
Example: RFS =0 (which is Short Frame Size)
Note: Valid only in DVB-S2 mode. If the unit is not locked, the query returns 'x'.
Query only.
Rx FEC coding type in the form x, where:
0=Viterbi + Reed-Solomon
1=LDPC
