Realization of a GPIB converter based on a Raspberry Pi

23.12.2020

An ethernet‑to‑GPIB (IEEE‑488) data bus converter has been realized on the basis of the Raspberry Pi, a widely used, single‑board computer. Today, such converters are commercially available to a very limited extent only. However, they are required to secure the control of well‑established measuring systems with a GPIB in the long term via more modern interfaces (USB, ethernet). In addition, this new development enables specific adaptations to particular measurement conditions as well as the further integration of logic elements that are specific to a given user or a given measurement station.

High‑end measuring instruments equipped with a GPIB (IEEE‑488) data bus are widely used at PTB. In new devices, this bus is, however, often replaced by ethernet, USB technology or other bus systems, so that providers of GPIB PC interfaces are increasingly disappearing from the market.

Based on a project of the University of Vienna (Austria), an interface converter has now been realized on the basis of the Raspberry Pi, a widely used, single-board computer, which allows high-end, well-established measuring instruments equipped with a GPIB to be connected to modern bus and transmission systems.

The device that we have developed also offers the possibility of integrating further logic elements and measurement sequences into the converter, and thus has the potential to be adapted to future bus developments.
