摘要
矢量网络分析仪做为微波测量领域一类重要仪器,提供的测量功能非常丰富,平均是矢量网络分析仪上的一种主要辅助测量手段,如果应用得当会在实际测量中发挥重要作用。结合在矢量网络分析仪上的开发经历,主要讨论平均的作用及工作原理,重点介绍平均测量手段的适用范围,并以实测数据的形式给出正确与否应用平均而带来的不同测量结果。
Vector network analyzer is an important instrument in microwave measurement area, the analyzer provides abundant test functions, averaging is an essential measurement function, and it may greatly improve the measurement results if used properly. The paper mainly discusses the effect and theory of averaging, when and how to use averaging is present either. Data and figures are provided to show that the measurement results are very different when using averaging properly or improperly.
