将 CF—920小型 FFT 分析仪与微型计算机通过 GP—IB 接口进行联机工作,是一种充分发挥设备效率,扩充设备功能的有效办法。简述了GP—IB 系统的组成、功能及其工作方式;介绍了 CF—920所具有的 GP—IB 接口功能及其用途;讨论了将 CF—920与HP—85B 微机联机进行时间记录数据相互传输的步骤;对联机实施中的一些具体接口操作命令给出了程序框图。
The CF-920 small FFT analyzer and microcomputer via the GP-IB interface for online work, is to give full play to equipment efficiency, expansion of equipment, an effective way. The composition, function and working method of GP-IB system are introduced briefly. The GP-IB interface function and its application of CF-920 are introduced. The connection between CF-920 and HP-85B microcomputer is discussed. Transmission steps; on-line implementation of some of the specific interface operation command gives the block diagram.
