介绍了为ＰＣ微机开发的一块ＧＰＩＢ接口卡和相应的控制软件，使得微机能够通过ＧＰＩＢ接口与Ｂ＆ Ｋ２０３４ 双通道信号分析仪进行实时通讯。讨论了ＧＰＩＰ接口卡的硬件原理、工作过程和协议层软件的设计及例程。利用这一实验装置可以充分发挥信号分析仪和微机各自的优势，达到对信号进行进一步分析的目的。本文最后给出了应用实例。
This paper introduces a GPIB interface card and corresponding control software developed for PC microcomputer, which enables the microcomputer to communicate with B & K2034 dual channel signal analyzer through GPIB interface in real time. Discusses the hardware principle of GPIP interface card, work process and protocol layer software design and routine. Using this experimental device can give full play to the advantages of the signal analyzer and microcomputer, to achieve the purpose of further analysis of the signal. At the end of this paper, the application examples are given.
