SCPI for Power Sources

The SCPI (Standard Commands for Programmable Instruments [wiki]) defines a standard for syntax and commands for use in controlling electronic devices such as measurement devices and power supplies.

Since mid 2021, all MCB Electronics products (AC Power Sources, DC Power Sources, Current Generators, …) come with this standard protocol over RS-232 and Ethernet, thus replacing the old (custom) ASCII protocol.

SCPI Programming Guides

Here you can find our Programming Guides, grouped by product family. The first chapters are a review of the standards and are based on

  • “IEEE Standard Codes, Formats, Protocols, and Common Commands for Use With IEEE Std 488.1-1987, IEEE Standard Digital Interface for Programmable Instrumentation”. In: Dec. 1992. doi: 10.1109/IEEESTD.1992.114468 (URL)
  • “Standard Commands for Programmable Instruments (SCPI)”. In: 1999 (URL)

while the other chapters are product specific.

Communication Interfaces Setup

SCPI is accessible over two different interfaces (RS-232 and Ethernet) on all our new Power Sources, as described in this guide:

Communication Interfaces Setup Guide

The document presents the available communication interfaces, their configuration, how to change their settings, and procedures to communicate using SCPI over each one of them.

SCPI Client

scpi client windows

Moreover, we developed a super lightweight application (single window, no installation required) to easily test your settings and to try SCPI commands both over RS-232 and Ethernet (TCP/IP).

LabVIEW Drivers for Power Sources

National Instruments Laboratory Virtual Instrument Engineering Workbench (LabVIEW) is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights. Considering that our Power Sources uses SCPI,  the integration in LabVIEW with NI-VISA is straightforward.

Here you can find the drivers to use our products with NI LabVIEW (Plug and Play drivers, project-style).

The projects listed here have been created with version 20.0.1, but they can be saved for previous versions (until 8.0) upon request.
