Abstract

It is complicated to test terminals supporting various communication modes such as 4G/5G, Tiantong satellite, and ad hoc networks, which requires various instruments such as the Tiantong comprehensive tester, LTE comprehensive tester, spectrum analyzer, power meter, and so on. In order to improve the test efficiency, a variety of comprehensive test platforms have been developed in recent years. This type of equipment uses embedded chips, integrates a variety of communication protocols, and completes data processing and index measurement in the digital domain by directly sampling the tested signal. To assess the accuracy of the data from such test platforms, a repeatability test and a comparison test are designed, and the test results from traditional instruments are modelled and processed as credible data. The results show that the critical difference can be used as the judgement benchmark to effectively assess the accuracy of the test data.
