RX LO
Frequency
RLO= 6 bytes 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)
