6012-12W Installation Manual
Optimizing Cross-Pol Isolation
6.
Access the Reflector Configuration
screen.
7.
Change the “Linear Offset” value by the
amount of difference recorded in step 4.
Examples:
Skew was 0.0, you increased it to 2.5 to optimize
TX polarization. You set Skew back to zero and
go to the Reflector Configuration screen where
you find Linear Offset to be 0.0, so you increase
Linear Offset to 2.5 degrees and click
Save.
Skew was 3.0, you decrease it to 1.0 to optimize
TX polarization. You set Skew back to 3.0 and go
to the Reflector Configuration screen where you
find Linear Offset to be 0.0, so you set Linear
Offset to minus 2 (-2.0) degrees and click
Save
.
8.
Double check with the NOC to assure
that cross-pol is still optimized.
9.
Conduct any other testing as directed by
the NOC (ie P1dB compression).
