Task F. Fine Azimuth Adjustment (Slimline ODUs Only)
To perform the fine azimuth adjustment:
1 Loosen the ODU’s azimuth lock-down screws.
2 Turn the ODU’s azimuth jack screw counterclockwise 2 turns.
3 On the FINE AZ ADJ screen, press SET REF to set the reference value.
The AIM sounds a confirmation tone and displays the reference value.
4 Zero out the readout dial on the azimuth jack screw.
5 Turn the azimuth jack screw clockwise until the meter sounds a confirmation
tone and the displayed signal power matches the reference value.
6 Refer to the ODU’s dial and use the AIM’s numeric keypad to enter the number
of turns it took to return to the reference value. Then press OK.
7 Zero out the readout dial on the azimuth jack screw.
Note: It will take around four turns to reach the
reference value.
Example: If it took four and a half turns to
return to the reference value, enter 4.50.
