1. Perform system setting shown in the above configuration
2. For downlink performance test, using signal analyzer, provide -20dBm/composite
power input to BIU, and set system gain to maximum level.
3. Connect all the unit like above configuration and turn the power on for all units and
make sure all the alarms in normal status by GUI monitoring.
4. Using spectrum analyzer and optic power meter, check output power for each unit as
described in the above configuration and check whether the output powers are in the
normal range.
5. For uplink performance test, using signal analyzer, provide -50dBm/band to remote unit
6. Connect all the unit like above configuration and turn the power on for all units and
make sure all the alarms in normal status by GUI monitoring.
7. Using spectrum analyzer and optic power meter, check output power for each unit as
described in the above configuration and check whether the output powers are in the
normal range.
8. Temporarily, turn the power off for all units.
9. Using spectrum analyzer, measure the input range from BTS/BDA if the range is
between -20dBm and +10dBm.
10. If the level exceeds the range, need to connect an attenuator with the front end of BIU
input to adjust the level in the corresponding range.
11. turn the power on for all units and make sure all the alarms in normal status by GUI
monitoring.
12. For system optimization, through GUI, adjust the all the parmaters such as ALC, AGC,
Shut down level, and offset values.
