LNB LO
Frequency

LLO=

6 bytes

Command or Query.

LNB Receive LO frequency information in the form xxxxxs, where:

xxxxx is the LO frequency, in the range of 3000 to 65000 MHz.

s is the sign for the mix (+ or – character)

All 0’s (000000) disables this feature.

Terminal Frequency = LNB LO RFQ

Example: LLO=06000- (LO is 6 GHz, high-side mix)
