摘要
分别用传统测试方法和用矢网测量S参数法测试了行波管的调幅调相转换系数,对两次测试结果进行了比较,并重点对矢网测试的误差进行了分析和讨论,确定了用矢网测量行波管AM/PM参量的方法。实际测试结果表明通过调整状态设置参量,用矢网测试行波管AM/PM参量的方法是高效可行的。
AM/PM conversion coefficients were measured by traditional method and the method based on vector network analyzer, respectively. The different measurement methods were compared. The results indicat- ed that the method based on vector network analyzer is feasible and efficacious by adjusted the settings of vector network analyzer.
