Abstract:
1. A method for using a radio-frequency test system to test an electronic device under test that contains transceiver circuitry and a tunable antenna having an adjustable antenna tuning element, the method comprising: placing the adjustable antenna tuning element in a plurality of tuning states to tune the tunable antenna; while the adjustable antenna tuning element is being placed in each of the plurality of states and while the transceiver circuitry is deactivated, gathering test data from the electronic device under test with the radio-frequency test system; and with the radio-frequency test system, gathering baseline test data by performing radio-frequency calibration on a plurality of reference electronic devices under test, wherein the adjustable antenna tuning element comprises at least one adjustable circuit selected from the group consisting of: a radio-frequency switch, a tunable resistive component, a tunable capacitive component, and a tunable inductive component.
