Radio frequency performance testing method and device for wireless equipment and tester

Abstract

The invention discloses a radio frequency performance testing method and device for wireless equipment and a tester, and the method comprises: collecting the 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 so as to form a virtual wire between an instrumentoutput port and a receiver port of the tested piece; and according to the throughput rate test signal, carrying out transmission through the virtual wire so as to carry out performance test on the tested piece and generate a radio frequency performance test result. According to the method, the virtual wire can be solved according to the power return information, the test efficiency is improved while the test accuracy is improved, and the test applicability is improved.

Description

technical field [0001] The invention relates to the technical field of wireless equipment performance testing, in particular to a radio frequency performance testing method, device and tester for wireless equipment. Background technique [0002] In the related art, it is customary to use conduction means to test the radio frequency performance of the wireless device. Specifically, such as figure 1 As shown, the performance of the antenna of the wireless device is first tested by the conduction method, and then the performance of the receiver is tested by connecting the conduction line to the receiver, so that the combination of the obtained results is considered as the radio frequency performance of the whole machine. [0003] However, the conduction test of the related art has the following problems: [0004] First: Since the conductive wire is connected to the conductive feed point of the DUT, it will change the RF matching of the DUT itself, which will change the perfor...

[0006] Third: In the normal working mode, the interference noise of the DUT itself can be coupled into the receiver through the antenna, causing certain interference to the receiver, but after the conductive connector is connected, the noise coupling cannot enter the receiver, resulting in test The result does not match the actual result;

[0007] Fourth, in 5G wireless terminals, due to the limited size of the device under test or the cost requirements, there are generally no RF connectors left, which makes it impossible to conduct conduction tests

[0008] Therefore, the conduction test of the related technology not only has certain errors, which reduces the test accuracy, but also has certain limitations, which need to be solved urgently
