Automatic test system of full electrical parameters for space traveling-wave tubes

摘要

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.
