Method and device for intermodulation interference test of wireless communication terminal of private network

Abstract

The embodiment of the invention provides a method and a device for intermodulation interference test of a wireless communication terminal of a private network. The method mainly comprises the following steps of according to the requirements of a test specification for the intermodulation interference test of the wireless communication terminal of the private network, selecting a circulator from a circulator group by a coaxial switch to engage, and / or selecting an attenuator from an attenuator group by a coaxial switch to engage; and connecting the circulator group with the attenuator group, enabling the circulator group to receive the inputted tested signal of the wireless communication terminal of the private network, enabling the engaged circulator and / or the engaged attenuator to process the tested signal, and enabling the attenuator group to output the processed 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 intermodulation interference test process of the wireless communication terminal of the private network is solved; and the system integration of all models of approved test links for radiation interference and radiation stray indexes in the wireless communication terminal of the private network is realized.

Description

Technical field [0001] The present invention relates to the technical field of private network wireless communication terminal testing, in particular to a method and device for performing intermodulation interference testing on private network wireless communication terminals. Background technique [0002] Private network terminal radio frequency automatic test system refers to an automatic test system that adopts computer control to automatically complete call establishment, link switching, signal measurement, data calculation and processing, and output test results. It is mainly used in the radio frequency index test of private network wireless communication terminals and Automatic test system construction, including digital radio, digital trunking, digital radio, analog radio and other private network wireless communication terminal radio frequency index test and automatic test system tower construction. [0003] At present, in the process of conducting private network model app...

Problems solved by technology

[0003] At present, in the process of intermodulation interference test for private network model approval for private network wireless communication terminals, for different intermodulation interference test items and standards, it is necessary to manually install corresponding radio frequency links to meet the test requirements. Sometimes, in In the process of completing an intermodulation interference test, 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.
