Isolating the transmit signal

To prevent signal cross talk, you use a procedure known as Automated Cross Polarization (ACP) to isolate the transmit signal from the receive signal. ACP is included in the installation software.

The ACP software operates in two different modes—manual or automatic fine pointing. The automatic mode takes a snapshot of the cross polarization isolation measurement, while the manual mode gives real-time feedback of cross polarization isolation measurement while adjusting the antenna. Passing the automatic test enables the transmitter. Once the transmitter is enabled, the site is ready to be registered.

The ACP method consists of using the manual and/or automatic fine pointing tests and adjusting the antenna by small increments (if necessary) until it passes the automatic ACP test.

Follow the general instructions below for the ACP tests. Use the installation software screens to initiate tests and see the test results.

First run an automatic ACP test:

1.Before running ACP tests, lock down all antenna adjustment nuts and bolts.

2.Initiate an automatic ACP test.

If the antenna passes this test, it is pointed and ready to be registered.

The following test is necessary only if the antenna fails the automatic ACP test:

1.Loosen the four polarization nuts one-quarter of a turn—just enough so you can adjust the polarization.

2.Using the software screen, initiate a manual ACP test.

3.When the test starts, make small, 1° or less changes in polarization while observing the transmitter isolation.

4.Peak the polarization to the highest possible transmitter isolation.

5.Tighten the four polarization nuts.

Note: When you adjust any one of the axes (polarization, elevation, or azimuth) you may also have to adjust one or both of the other axes.

6.If the antenna passes the manual test, stop the test and run the automatic ACP test again.

If the antenna passes the automatic test, it is pointed and ready to be registered.
