• LNB 22 KHZ SETUP
The receiver controls the LNB band by sending a 22KHz signal. When the
signal is sent, the LNB uses its High Band Local Oscillator (L.O.). When the
signal is not sent, the LNB uses its Low Band L.O.
The local oscillator is used to convert the signal from Ku-Band or C-Band
to L-Band. Two local oscillators exist one for each band to leverage full
spectrum.

When frequency drift compensate mode is enabled, the IRD tracks
frequency drifts which are caused by a drift in the LNB L.O. and caused by
environmental changes.
