Arguments
Description of Arguments
or Response

Rx Modulation Type, where:
0 = Rate 3/4
1 = Rate 7/8
2 = Rate 3/5
3 = Rate 4/5
4 = Rate 5/6
5 = Rate 8/9
6 = Rate 9/10
7 = Rate 2/3
8 = Rate 1/2
Example: RCR=0 (which is Rate 3/4)
*NOTE: Please refer to Ch.8 for a list of available code rates for
each mode. If the demodulator is set to DVB-S2 mode, this
command is query-only because the code rate is automatically
detected, but if the unit is not locked, the query returns 'x'.
Rx Symbol Rate, where:
s=Symbol Rate in Msps
Example: RSR=20.000000 (20 Msps.)
*NOTE: Please refer to Ch. 8 for available symbol rates for each
mode.
Rx Frequency (in MHz)
52 to 88 MHz, and 104 to 176 MHz (70/140 Modulator)
950 to 1950 MHz (L-Band Modulator)
Resolution=100Hz.
Example: RFQ=0950.0000
