Automatic ACP test
Initiate the automatic ACP test using the installation software by
selecting the Automatic cross-polarization test. If the automatic
ACP test passes and the peak signal strength in maintained to
within 3 points on the signal strength scale, the antenna is pointed
and ready to be registered.
If the antenna fails the automatic ACP test, follow these steps:
1. Initiate a manual ACP test.
2. When the test starts, make small, 1
°
or less changes in the tilt
angle while observing the transmitter isolation.
3. Peak the tilt angle to the highest possible transmitter
isolation.
4. Tighten the tilt lockdown nuts.
5. If the antenna passes the manual test, stop the manual test and
run the automatic ACP test again.
6. Check the signal strength.
If the antenna passes the automatic ACP test and maintains signal
strength within 3 points on the signal strength scale, it is pointed
and ready to be registered.
If the antenna passes the automatic ACP test, but the signal
strength drops more than 3 points after the test, you must repeat
the fine adjustments for azimuth and elevation:
1. Repeat the fine adjustments for both azimuth and elevation to
maximize the signal strength.
2. Repeat the automatic ACP test.
3. Check the signal strength.
If the antenna passes the automatic ACP test and maintains signal
strength within 3 points on the signal strength scale, it is pointed
and ready to be registered.
If the antenna still does not meet both criteria, repeat very small
tilt, azimuth, and elevation adjustments and ACP tests as many
times as necessary until you have peaked the signal and the
antenna passes the automatic ACP test and signal strength is
maintained within 3 points.
Important:
When you are finished pointing the antenna, lock
down all pointing adjustments. All adjustment points are shown
in Figure 48 on page 65.
