Description of Arguments
Command or Query.
Sets or returns LNB Rx LO frequency information in the form xxxxxs, where:
xxxxx=LO frequency: 03000 through 65000 MHz, or 00000=Off
s=sign for the MIX (+ or –)(See Note 1)
NOTES:
1) Negative mix induces a spectral inversion.
2) For additional information see Chapter 6 for LO, MIX, and Spectrum Settings.
3) Rx Terminal Frequency=RX LO ± modem RFQ (see below)
Query only.
Returns Rx Terminal Frequency (the frequency, in MHz, being received from the satellite) in the form
xxxxx.xxxx.
Resolution=100 Hz
NOTES:
1) For additional information see Chapter 6 for LO, MIX, and Spectrum Settings.
2) Returns 00000.0000 if LNB LO is zero
EXAMPLE: <0/RTF? >0/RTF=11650.2249 (MHz)
Command or Query.
Sets or returns Rx Alpha in the form x, where:
0=Rx Alpha=0.35 (DEFAULT)
1=Reserved
2=Rx Alpha=0.12
3=Reserved
Query only.
Allows remote access to the Aggregate Rx Information Rate in the form ddddd.ddd
Query only.
Allows remote access to the IP portion of the Rx Information rate in the form ddddd.ddd
