LNB Polarity
This control is primarily used in “Universal” LNB
applications. The LNB Polarity control allows for
LNB polarization selection; the 13VDC source will
select the Vertical polarity and the 18VDC source
will select the horizontal polarity. For typical “C”
and “Ku” band applications, the 18 VDC option is
recommended.
H(18V)
V(13V)
LNB Tone
This control is used only for Universal LNB
applications. A universal LNB can route the high
or low band from either polarity to the IRD. The
high band is selected by enabling the 22 kHz
tone and the low band is selected when the 0 Hz
tone is enabled.

Downlink
Allows the operator to enter the satellite
downlink frequency. The value for the Downlink
frequency is used with the Local Oscillator
frequency to calculate the L-Band frequency. The
Downlink and Local Oscillator frequencies can be
used to determine if spectrum inversion occurs
using the following rules. If the Downlink
frequency is less than the Local Oscillator
frequency, then spectrum inversion does occur.
