METHOD FOR CALIBRATING AN OVER-THE-AIR (OTA) TEST SYSTEM FOR TESTING MULTIPLE RADIO FREQUENCY (RF) DATA PACKET SIGNAL TRANSCEIVERS

摘要

Method for calibrating an over-the air (OTA) test system for testing multiple radio frequency (RF) data packet signal transceiver devices under test (DUTs), as well as using such a calibrated OTA test system for performing such tests. Calibration is achieved by placing a known good device (KGD) in multiple defined locations within the OTA test system, radiating the KGD with RF test signals at each location, and collecting from the KGD at each location channel quality information identifying optimal RF test signal sub-band channels for ensuring reliable communications within the test system. Use of such system includes placing multiple DUTs at the defined locations within the OTA test system and communicating with them wirelessly via the identified optimal RF test signal sub-band channels.
