PyVISA is a Python package that enables you to control all kinds of measurement devices independently of the interface (e.g. GPIB, RS232, USB, Ethernet). As an example, reading self …

Introduction to PyVISA - Learn how to control measurement instruments like oscilloscopes using Python and SCPI commands.

Jan 13, 2026 · In addition, Python can be used to directly access most bus systems used by instruments which is why one can envision to implement the VISA standard directly in Python (see the PyVISA …

PyVISA is both a Python wrapper for VISA shared libraries but can also serve as a front-end for other VISA implementation such as PyVISA-Py.

Python wrapper for VISA library The readings are on the chart Control oscilloscopes, multimeters, and thousands of instruments with Python. Works with USB, Ethernet, GPIB, RS232.

PyVISA includes a backend that wraps the National Instruments’s VISA library. However, you need to download and install the library yourself (See NI-VISA Installation).

PyVISA presentation, a Python wrapper for the VISA driver that enables controlling measurement instruments using Python.

This example already shows the two main design goals of PyVISA: preferring simplicity over generality, and doing it the object-oriented way. After importing visa, we create a ResourceManager object.

PyVISA Windows installation - NI-VISA drivers, Python environments, corporate setups, troubleshooting, and configurations for instrument control.

The simulation backend (pyvisa-sim) is useful for writing drivers to simulated devices if the instrument is not available.This can be useful for testing purposes.
