LNB 22KHZ
The LNB-22KHz menu enables selecting between LNB low band and high band
reception, by generating a 22 kHz signal that is sent to the LNB for this purpose.
The following figure illustrates the LNB 22KHz screen.

reception is selected
• ON (High Band) - the 22 kHz signal is generated and high band reception
is selected.
INPUT SIGNAL SOURCE
The Input Signal Source menu selects the RF interface source through which to
acquire the signal to be received. This menu exists only in Dual RF Input IRD-
2900 devices. The following figure illustrates the Input Signal Source screen.

Source
• IN-A – the IRD-2900 receives the input signal from RF IN 1 interface
• IN-B - the IRD-2900 receives the input signal from RF IN 2 interface
FREQ DRIFT COMPENSATION
The IRD-29000 uses Freq Drift Compensation Feature to automatically correct
inaccurate frequencies inserted by the operator.
When the operator sets the receiver frequency, the IRD-2900 checks whether
the inserted frequency is set to the optimal frequency. When a deviation is
detected, the IRD-2900 calculates the offset from the original setting and
enables correcting it.
Turning on the Freq Drift Compensation in the following menu activates the
automatic frequency adjustment. When Drift compensation is turned off, the
device uses the original frequency setting that was inserted by the operator.
