摘要
分析了现有的自动测量线的优缺点。在传统测量线的基础上,基于美国国家仪器(NI)的实时处理系统sbRIO-9642,通过LabVIEW开发了具备实时远程控制功能的多功能微波自动测量仪。实现了测量对象的实时控制,以及测量过程的远程控制。在测量大驻波比的终端负载时,改进了K倍最小法,提高了测量精度。同时,从理论上探究了利用传统测量线实现多频率测量的方法,该方法可以用于检测多路未知信号的频率,具有较强的实用性和创新性。
Both advantages and disadvantages of the existing automatic measuring line are investigated. Based on the traditional measuring line, a multifunctional microwave automatic measurement system with real-time and remote control is developed by using the National Instruments real-time operating system sbRIO-9642. The real-time control of the measurement objects is realized, as well as remote control of the measurement process. When terminal load of high voltage standing wave ratio （VSWR） is measured, the K times minimum method is ameliorated, and the measurement accuracy is increased. Meanwhile, a method to realize multi-frequency meas- urement is explored by using traditional measuring line. The proposed method can be used to detect multichan- nel unknown signals and has the practical and innovative value.
