LNB 22 KH
The receiver controls the LNB band by sending a 22 kHz 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.

The PVR 6000 uses Freq Drift Compensation to automatically correct
inaccurate frequencies set by the operator.
When the operator sets the receiver frequency, the PVR 6000 checks whether it
is set to the optimum frequency. When a deviation is detected, the PVR 6000
calculates the offset from the original setting and enables correcting it.
Turning on the Freq Drift Compensation activates the automatic frequency
adjustment. When Drift compensation is turned off, the device uses the original
frequency setting that was inserted by the operator.
