5.
Remove the power meter from the variable attenuator and connect the variable atten-
uator to the radio antenna port.
6.
Measure the AGC voltage as measured on the RXU test point as well as the RSL read-
ing at the antenna port as displayed on the computer/terminal (Screen 005.) Record
these values in Table 5-J. Compare the RSL reading with the power meter reading. The
difference in the two readings is a calibration factor.
7.
Change variable attenuation and record corresponding AGC voltage as measured on
the RXU test point as well as the RSL reading at the antenna port as displayed on the
computer/terminal. Continue this process until BER reaches 10
-6
. Record these values
in Table 5-J.
8.
For a protected system, set B side on-line and lock the state of all modules (TX and RX
direction) at the local and remote terminals by using the computer/terminal at the Local
Access Port. Repeat Steps 2 through 7 for the B side radio.
9.
Remove the variable attenuator and connect the antenna feed to the radio antenna port
Set local and remote path switching to AUTO, and return APC to AUTO (Screen 087)
for normal operation.
