Ejector lever

Multi-meter

Procedure

1.Power off the vertically polarized ODUs at both ends of the

radio link, power on the horizontally polarized ODUs at both ends

of the radio link, and thus ensure that the antennas transmit

horizontally polarized signals.

2.Adjust the azimuth angle and elevation angle of the antennas at

both ends and ensure that the main lobe of the horizontally

polarized signals is aligned with the antenna.


41/61



3.Measure the RSL (P1) of the horizontally polarized signals at

the local end.

4.Adjust the feed boom at the local end, and ensure that the RSL

of the vertically polarized signals reaches the lower threshold (P2).

5.Record the angle (D1) of the current feed boom.

6.Power off the horizontally polarized ODUs at both ends

of the radio link, power on the vertically polarized ODUs at

both ends of the radio link, and thus ensure that the

antennas transmit vertically polarized signals.


42/61



7.Measure the RSL (P3) of the vertically polarized signals

at the local end by referring to 3.

8.Power on the horizontally polarized ODU at the local end,

and calculate the level (P4) of the horizontally polarized

signals received at the local end by referring to 4. The

calculated XPD2 (XPD2 = P3 P4) should not be less than

30 dB.

9.Record the angle (D2) of the current feed boom.
