PyVISA: Control your instruments with Python¶ 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-identification from a Keithley Multimeter with GPIB number 12 is as easy as three lines of Python code:

I don't know about pyvisa either, but I have pretty similar scripts to interface instruments with VXI. In that case, the talking is done through a tcp socket and not closing it may lead to problems on the next run of the script. However, it is possible the pyvisa takes care of these things for you.

Source Distributions vs Wheels ¶ pip can install from either Source Distributions (sdist) or Wheels, but if both are present on PyPI, pip will prefer a compatible wheel. Wheels are a pre-built distribution format that provides faster installation compared to Source Distributions (sdist), especially when a project contains compiled extensions.
