Tune Up Procedure
Tune-up procedure
During manufacturing each Device is individually calibrated. Measurement is performed in a fully
calibrated setup using an Agilent 8960 base station simulator (system tester). Measurement
procedure is outlined below:
Measurement Procedure:
1. Set the device to nominal operating voltage and on a predefined channel in a special test mode.
2. The actual output power is measured at several power levels.
3. The gain factors of each individual device are adjusted until the target value is met.
The appropriate gain control settings for each output power level are stored in each device
individually.
The user has no possibility to change these settings.
4. The maximum gains of each individual device are adjusted and measured until the target value
is met. The production target power with tolerance compiles with the maximum power in test report.
Target Value is Average Output Power Value
