简要讲述了GPIB接口规范,对GPIB专用芯片NAT9914的结构及其工作原理进行了说明.我们使用NAT9914设计了一种用于程控仪器的GPIB接口板,并给出了GPIB接口板的程序设计流程.
The interface specification of GPIB is simply described in this paper. The structure and working theory of GPIB interface chip nat9914 are also given. Then, we designed a kind of GPIB interface card using nat9914 for programmable instrument, and software flow when designing the GPIB program.
