Key technology research and product development of 5G test instruments

Abstract： With the promotion of 5G technology R & D tests and product R & D tests, as a support of the development of the industry, the test instruments have entered the fast development track. Domestic manufacturers have successfully developed 5G communication test instruments such as base stations, terminals, outfields and core networks. This article introduces the key technology breakthroughs and latest product achievements of 5G communication test instruments, including high-performance 5G communication test platform design and manufacture, multi-standard 5G NR physical layer test, 5G heterogeneous network air interface protocol analysis, microwave and millimeter wave test and calibration and other key technologies, also introduces the performance of test instruments such as base station test, terminal comprehensive test and air interface monitoring. These test instruments are important in every link of 5G communication industry chain, and provide strong support for the rapid development of the industry.
