本标准规定了通过IEEE 488.1总线连接的设备使用的一组代码和格式。本标准还定义了实现独立于应用程序的设备相关信息交换所需的通信协议，并进一步定义了仪器系统应用中有用的通用命令和特性。本标准旨在直接适用于中小型仪表系统。它适用于主要由测量、刺激和带有仪表控制器的互连设备组成的系统。本标准也适用于仪器系统环境范围之外的某些设备。除了定义各种依赖于设备的消息外，本标准还扩展并进一步解释了IEEE Std 488中包含的某些接口功能。 1同时保持与该标准兼容。

This standard specifies a set of codes and formats to be used by devices connected via the IEEE 488.1 bus. This standard also defines communication protocols necessary to effect application independent device-dependent message exchanges and further defines common commands and characteristics useful in instrument system applications. This standard is intended to apply directly to small-scale to medium-scale instrument systems. It applies to systems comprised mainly of measurement, stimulus, and interconnect devices with an instrumentation controller. The standard may also apply to certain devices outside the scope of the instrument system environment. As well as defining a variety of device-dependent messages, this standard extends and further interprets certain interface functions contained in IEEE Std 488.1 while remaining compatible with that standard.
