The GP-IB Interface Bus

The GP-IB Interface Bus

The General Purpose Interface Bus is the interface used for communication between a controller and an external device, such as the Agilent 81130A. The GPIB conforms to IEEE standard 488-1987, ANSI standard MC 1.1, and IEC recommendation 625-1.

If you are not familiar with the GPIB, please refer to the following books:

•The Institute of Electrical and Electronic Engineers: IEEE Standard 488.1-1987, IEEE Standard Digital Interface for Programmable Instrumentation.

•The Institute of Electrical and Electronic Engineers: IEEE Standard 488.2-1987, IEEE Standard Codes, Formats, and Common Commands for Use with IEEE Standard 488.1-1987.

In addition, the commands not from the IEEE 488.2 standard are defined according to the Standard Commands for Programmable Instruments (SCPI). For an introduction to SCPI and SCPI programming techniques, refer to the following document:

•The SCPI Consortium: Standard Commands for Programmable Instruments, published periodically by various publishers. To obtain a copy of this manual, contact the SCPI Consortium:
