摘要
针对因螺旋线行波管慢波线的结构特殊,导致其管内输能机构和切断衰减器的反射系数不易测量的问题,提出了利用多点法对输能机构和切断衰减器的反射系数进行测量的方法,并讨论了测试中所用探针反射系数的测试技术。该方法具有无损伤、测试方便等优点,也可用于其他类似特殊结构反射系数的测量。
A new application of multi-point method is presented in this paper, which is for the measurement of “cold test parameters”, the reflection coefficients at the output termination and attenuator of helix Traveling Wave Tube (TWT). The measurement method of the reflection coefficient of the probe used in the measurement of “cold test parameters” is also discussed. The method is nondestructive and easy, and can also be used in other measurements of the reflection coefficients of device which has similar special structure.
