IEEE-488

IEEE-488, also known as GPIB or HP-IB, comprises a set of standards which allows various test and measurement gear to be controlled and queried remotely.

The following standards are involved:

• IEEE-488.1 mechanical, electrical and basic protocol
• IEEE-488.2 formats and common commands
• SCPI standard commands, built on top of IEEE-488.2

While IEEE-488.1 defines the "Centronix-style" parallel connector, the other standards are in fact seen over other types of connections: RS-232, IEC-style parallel connectors, and so on.

Sigrok aims to support all of this: all of the command sets, on any device supporting them, across any interface.
