本标准将以IEEE标准488.1-1987中定义的接口功能为基础，以定义一组接口功能，使符合本规范的设备之间能够实现更高的传输速率，同时仍保持这些设备与现有IEEE标准488.1设备通信的能力。本标准范围内的主题包括:IEEE标准488.1中定义的接口功能的扩展；定义新的接口功能；IEEE标准488.1中定义的远程消息代码的可能扩展；计算在不同距离实施新协议所需延迟的指南。

This standard will build on the interface functions defined in IEEE Std. 488.1-1987 to define a set of interface functions that will enable higher transfer rates between devices adhering to this specification while still maintaining the ability for these devices to communicate with existing IEEE Std. 488.1 devices. Topics within the scope of this standard include: Extensions to the interface functions defined in IEEE Std. 488.1; Definition of new interface functions; Possible extensions to the remote message codes defined in IEEE Std. 488.1; Guidelines for calculating delays required to implement the new protocol at different distances.
