Title:

RADIO FREQUENCY PERFORMANCE TESTING METHOD AND APPARATUS OF WIRELESS DEVICE, AND TESTER

Document Type and Number:

WIPO Patent Application WO/2020/134447

Kind Code:

A1

Abstract:

Disclosed are a radio frequency performance testing method and apparatus of a wireless device, and a tester. The method comprises: collecting power return information of a tested piece; obtaining a propagation matrix according to the power return information, and obtaining a loaded inverse matrix according to the propagation matrix to form a virtual wire between an instrument output port and a receiver port of the tested piece; and performing transmission by means of the virtual wire according to a throughput rate test signal to perform performance testing on the tested piece, and generating a radio frequency performance test result. According to the method, the solving of the virtual wire can be realized according to the power return information, thereby improving the testing accuracy and efficiency, and improving the testing applicability.
