Problems solved by technology

[0003] At present, in the process of 2G and 3G radio frequency conformance testing for wireless communication terminals, for different radio frequency test items and standards, it is necessary to manually install corresponding radio frequency links to meet the test requirements. Sometimes, after completing a radio frequency test In the process, multiple test links need to be carried manually. This test method is not only inefficient, but also manually carries test links, which will introduce measurement errors and affect the accuracy of test results.
[0004] If the link is manually loaded and tested, measurement errors will be introduced, which will affect the accuracy of the test results
Moreover, at this stage, the function of the RF conformance switching unit is single, and it is impossible to complete the test indicators of all standards for model approval.

Abstract

The embodiment of the invention provides a method and a device for radio frequency consistency test of a wireless communication terminal of a public network. The method mainly comprises the following steps of according to the requirements of a test specification for the radio frequency test of the wireless communication terminal, selecting a function link from a function link group by a coaxial switch to engage, and selecting a filter from a filter group by a coaxial switch to engage; and enabling the function link group to receive the inputted tested signal of the wireless communication terminal, compensating the tested signal by the engaged function link, transmitting the compensated tested signal to the filter group, enabling the filter group to transmit the processed tested signal to the function link group, and enabling the function link group to output the filtered tested signal. The method and the system provided by the embodiment of the invention have the advantages that the problem of respective manual building of different test links due to different test specifications in the radio frequency consistency test process of the wireless communication terminal is solved; and the system integration of all models of test links for the radio frequency consistency test of a 2G / 3G (second generation / third generation) wireless communication terminal is realized.
