Description: PyVISA-py
=========
A PyVISA backend that implements a large part of the "Virtual Instrument Software
Architecture" (VISA_) in pure Python (with the help of some nice cross platform
libraries python packages!).
Description
-----------
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.
Starting from version 1.6, PyVISA allows to use different backends. These backends can be
dynamically loaded. PyVISA-py is one of such backends. It implements most of the methods
for Message Based communication (Serial/USB/GPIB/Ethernet) using Python and some well developed,
easy to deploy and cross platform libraries
.. _VISA: http://www.ivifoundation.org/Downloads/Specifications.htm
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 2.6 and 2.7, 3.2+)
- PyVISA 1.6+
Optionally
- PySerial (to interface with Serial instruments)
- PyUSB (to interface with USB instruments)
- linux-gpib (to interface with gpib instruments, only on linux)
Installation
--------------
Using pip:
$ pip install pyvisa-py
