is a cross-platform Python package that has been written by Torsten Bronger:
The PyVISA package enables you to control all kinds of measurement equipment through various busses (GPIB, RS232, USB) with Python programs.
PyVISA is used to interface with electronic devices that adhere to the
specification. VISA is defined by the
Interchangeable Virtual Instrument (IVI) Foundation, and is
used to create a standardized interface to a variety of instrumentation
control buses. Electronic devices such as voltmeters, oscilloscopes,
temperature sensors, power supplies, motors and much more can be
accessed by VISA.
PyVISA includes the
vpp43 VISA library implementation, which deals with the low-level
PyVISA can work with a number of adapters such as those from
National Instruments, Agilent, and Tektronix.
Assuming one has the required hardware and driver installed, the
software appears to be fairly easy to use. The
examples for performing data acquisition from Python.
More complex applications, such as
an open-source instrumentation control and display program, have been
built around PyVISA.
Version 1.1 of PyVISA
was recently announced:
"Yesterday I released version 1.1, which works much better together
with older VISA implementations. Moreover, we finally have reports
from Linux users. They successfully used PyVISA with Linux +
NI/Tektronix GPIB hardware."
PyVISA looks to be an important tool for those who wish to perform
instrumentation control functions from a Linux machine.
