Preliminary study on measurement of output hot-VSWR in Traveling Wave Tubes

This paper proposes a method for the measurement of output port hot-VSWR in TWT. This method is aimed at solving the following problems in the traditional test method: 1) test equipment is not common; 2) test process may damage the traveling wave tube; 3) test process is complicated. In addition, this method not only improves the test convenience and security, but also greatly improves the test accuracy and test speed.
