PyVISA-sim is a PyVISA backend that simulates a large part of the “Virtual Instrument Software Architecture” (VISA).
Description
PyVISA started as a wrapper for the NI-VISA library and therefore you need to install the National Instruments VISA library in your system. This works most of the time, for most people. But sometimes you need to test PyVISA without the physical devices or even without NI-VISA.
Starting from version 1.6, PyVISA allows to use different backends. These backends can be dynamically loaded. PyVISA-sim is one of such backends. It implements most of the methods for Message Based communication (Serial/USB/GPIB/Ethernet) in a simulated environment. The behaviour of simulated devices can be controlled by a simple plain text configuration file.
VISA and Python
Python has a couple of features that make it very interesting for measurement controlling:
Python is an easy-to-learn scripting language with short development cycles.
It represents a high abstraction level, which perfectly blends with the abstraction level of measurement programs.
It has a very rich set of native libraries, including numerical and plotting modules for data analysis and visualisation.
A large set of books (in many languages) and on-line publications is available.
Requirements
Python (tested with 3.8 to 3.11)
PyVISA 1.11+
Installation
Using pip:
$ pip install -U pyvisa-sim
or install the development version:
$ pip install git+https://github.com/pyvisa/pyvisa-sim
PyVISA is automatically installed if needed.
