DIB-500 R4.1
Commissioning
Setting a cavity coupler to the TX frequency
122
Installation and Operation Manual 90DIB500IM02 – 5.2
Maximum transmitter output measurement
The maximum transmitter output measurement must always be greater than the value
produced by the following formula: Maximum transmitter output configuration - 5 dBm.
10. Tighten the hand wheel on the front of the corresponding cavity coupler again.
11. Enter the
car shutdown x
command to disable the measured carrier again;
x corresponds to the carrier number.
12. Repeat the previous work steps beginning with step 7. for all the carries to be
measured.
13. Remove the antenna cable or the dummy load from the adapter of the measuring
probe.
14. Remove the corresponding measuring equipment and reconnect the antenna
cable.
15. Enter the
p s sbue sbcc 02 0x XXXXX
command to reset the output power to
the permissible value (network specific);
x corresponds to the carrier number;
XXXXX corresponds to the power in W. For information on the permissible value,
please refer to the project-specific documents.
16. Enter the
car sw-reset x
command to enable all the carriers again;
x corresponds to the carrier number.
17. Enter the
bsca la
command to check whether the corresponding carriers have
really been enabled again.
➥
The following output is displayed:
bsca la'puc_1'-BSC 10.32.35.17 (5100) >bsca la
Active Alarms of component BSC:
---------------------------------
none
Active Alarms of component CAR1:
---------------------------------
none
Active Alarms of component CAR2:
---------------------------------
none
Command is okay
Take note of the status
A carrier is enabled when the output for the corresponding carrier shows none. If the
carrier has not been enabled, you have to repeat the command.
