Calibrate the Base Station
Calibrating the Base Station detects the phase differential between the antennas and matches the
output power across all antennas in the RFS. The calibration procedure must be performed at
least three times to ensure validity. Ensure that the BTS has been powered on with the power
amplifiers on for at least fifteen minutes to allow them time to warm up and stabilize.
Calibration Procedure

Configuration Guide, as needed.
Step 1. On the Test EMS, click on the Server icon to start the EMS Server.
