“…As a key component of satellite communication and space-borne transponder, the space TWT is the most important system unit in satellite system and is responsible for the amplification, forwarding and transmission of microwave signals. However, due to extremely stringent working environment [1,2] and high-performance requirements [3,4], space TWTs are the electric vacuum device with the highest performance requirement [5].…”

“…The process of data recording is scattered and data arrangement is tedious, which cannot ensure the objectivity of the test data. (2) The test data only record the final result data, lacking the process data, which may lead to some phenomena which cannot be observed in time and cannot ensure the integrity of the test data. (3) A comprehensive test needs to cooperate with a variety of test equipment and devices, which puts forward higher requirements for testers.…”

In the development of space traveling wave tubes (TWTs), there have been many problems in testing their performance, such as too many test sections, complex operation processes, long test times and large amounts of test data. In this paper, an integrated test system for space TWTs is studied to achieve an accurate, fast and complete test of its full electrical parameters. The system can automatically switch the test instruments according to the tested contents, which eliminates the manual operation of setting the test bench and reduces personal error. Then, the one-button testing of full electrical parameters is realized by means of automatic test software of space TWTs, which greatly improves the test efficiency. Moreover, a standardized and scientific test data management system is established to ensure the integrity and objectivity of the test data. Finally, the testing accuracy and stability of the system are verified by data comparison.
