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.
