Polarization Parameters
The Polarization Angle is based on 2 values:
• PL Pot Factor
• PL Pot Zero
PL Pot Factor is an A/D value from the potentiometer which allows the iNetVu™ Mobile
Software to convert the A/D value of the Potentiometer into an equivalent angle. The PL
Pot Factor should vary approximately +
15% from the Default values below.
PL Pot Zero is an A/D value from the potentiometer which physically determines where
the iNetVu™ Mobile Software places Polarization Angle 0°. The PL Pot Zero may vary
approximately +
15% from the Default values below.
The PL Pot Factor and PL Pot Zero are calculated during the Polarization Calibration
process.

Disable Rotation
An option that is used for circular-signaled frequency bands such as X-Band or Ka-Band.
It will only be available for the A0660A and A1800A Mobile Platforms. By default, the
Polarization will be disabled for the A0660A Mobile Platform, and enabled for the
A1800A Mobile Platform. This function can only be accessed via CONFIG Mode, and
the Polarization ST Limit Switch must be closed and permanently display ST.
