Abstract
A method for testing radio frequency performance of a wireless device is provided. Power level reporting information of a device under test is obtained. A propagation matrix is obtained based on the power level reporting information. An inverse matrix is obtained based on the propagation matrix to form a virtual cable between an output port of an instrument and a receiver port of the device under test. A throughput test signal is transmitted through the virtual cable to perform a performance test on the device under test and to obtain a test result of the radio frequency performance.
