Transponder
Frequency (KHz)
Ku/C-Band Frequency Selection
Input of the Satellite Transponder (Ku or C Band)
frequency for the DSNG IRD and QPSK IRD Receivers in
the Ku/C Band.

LNB Local
Oscillator (MHz)
LNB Oscillator Setup
The LNB Local Oscillator (LO) provided with the receiving
antenna unit, down converts the carrier frequency of the
incoming signal to a range acceptable to the receiver. This
is achieved by down converting the frequency of the
incoming signal.
However, for display accuracy, the selected LNB Local
Oscillator frequency must be in accordance with the
frequency of the receiving antenna installed in the system
(disregarding the frequency provided at the IRD input).
Available Options: Universal (9750-10600), Wide Band
(9750-10750), DiSeQC (9750-10600), 5150 (C Band).

LNB Power
Supply
LNB Power Supply Setup
The polarization of the receiving antenna is determined
according to the requirements in the broadcast program
parameters. The IRD controls the polarization of the
receiving antenna by means of the voltage provided to the
LNB Power Supply.
Available options:
OFF: Power Supply off.
14 (Vertical): 14 V Power Supply / Vertical Polarization.
18 (Horizontal): 18 V Power Supply / Horizontal
Polarization.
