摘　　要：一些早期精密网络分析仪只是部分功能不足,但仍有很高测量精度,为了使它们继续发挥作用,本文通过GPIB接口建立了典型微波网络分析仪与PC间的通信,并在PC上利用LabVIEW集成环境开发了虚拟微波网络分析仪程序;该虚拟程序采用通道测量字技术扩展了原仪器的测量通道;置换并升级了其数据存储方式,增加了反向存储能力;另外,还利用指令存储数组使典型网络分析仪实现了一键式自动测量。这样不仅弥补了其原来的不足,还扩展了其部分功能。除使其更便于操作外,还提高了测试效率。Some old precise microwave vector network analyzers can still work with high precision, though they lack some important new functions. To make full use of these instruments right along, this paper builds the communication between a type microwave network analyzer and a PC by GPIB interface. It develops the VI of microwave network analyzer based on LabVIEW on the PC. And the VI extends the number of the channel of the instrument by the technique of the channel measuring words, displaces and promotes the way that it stores data, and also realizes auto- measurement with a typical VNA conveniently by technique of storing command array. Thus it not only makes up the lacking of the original instruments, but also extends the functions of them. Besides making them operating more conveniently, it also improves their efficiency of working.
