Field Calibration
The following procedures can be carried out in the field.
In addition, the following procedures should be carried out if the base station
fails a modulation fidelity test.
Service Center Calibration
The following procedures may need to be carried out after a module has been
serviced. They are in addition to the field procedures listed above.
