Patent ID: 8831529

Claim:
A method of using a test system to calibrate an electronic device, wherein the test system includes a radio communication tester and a test chamber in which the electronic device is placed during calibration, the method comprising: while the test chamber is set to provide a first a first internal chamber temperature, obtaining baseline measurement data from the electronic device with the radio communication tester; while the test chamber is set to provide a second internal chamber temperature that is different than the first internal chamber temperature, obtaining additional measurement data from the electronic device with the radio communication tester, wherein the electronic device includes wireless communications circuitry configured to generate radio-frequency test signals during calibration, and wherein obtaining the baseline measurement data and the additional measurement data comprises obtaining radio-frequency output power measurements associated with the radio-frequency test signals using the radio communication tester; and computing calibration data for the electronic device by comparing the additional measurement data to the baseline measurement data.
