This library provides Python VISA bindings for GPIB, RS232, and USB instruments.

PyVISA started as wrapper for the NI-VISA library and therefore you need to install National Instruments VISA library in your system. This works most of the time, for most people. But NI-VISA is a proprietary library that only works on certain systems. That is when PyVISA-py jumps in.

This package provides Python 3 bindings for pyvisa-py.
