Python VXI-11 Readme

IMPORTANT: this is a fork of python-vxi11 package which is not maintained anymore. It was modified to support Python>=3.13, removed compatibility with Python 2 and modernized the packaging a little bit.

Introduction

Python VXI-11 provides a pure Python VXI-11 driver for controlling instruments over Ethernet.

Requirements

• Python 3.9 or newer
• Python 3.13 and newer require the packaged py-xdrlib dependency

Installation

Extract and run

python -m pip install .

For development and tests, use:

.venv/bin/python -m pip install -e ".[test]"
.venv/bin/python -m pytest

Usage examples

Connecting to Agilent MSO7104A via LXI:

import vxi11
instr =  vxi11.Instrument("192.168.1.104")
print(instr.ask("*IDN?"))
# returns 'AGILENT TECHNOLOGIES,MSO7104A,MY********,06.16.0001'

Connecting to Agilent E3649A on GPIB address 5 via HP 2050A GPIB bridge:

import vxi11
instr = vxi11.Instrument("192.168.1.105", "gpib,5")
print(instr.ask("*IDN?"))
# returns 'Agilent Technologies,E3649A,0,1.4-5.0-1.0'

Connecting to Agilent MSO-X 3014A via USBTMC via Agilent E5810 GPIB bridge:

import vxi11
instr = vxi11.Instrument("192.168.1.201", "usb0[2391::6056::MY********::0]")
print(instr.ask("*IDN?"))
# returns 'AGILENT TECHNOLOGIES,MSO-X 3014A,MY********,02.35.2013061800'

It is also possible to connect with VISA resource strings like so:

import vxi11
instr =  vxi11.Instrument("TCPIP::192.168.1.104::INSTR")
print(instr.ask("*IDN?"))
# returns 'AGILENT TECHNOLOGIES,MSO7104A,MY********,06.16.0001'

and:

import vxi11
instr = vxi11.Instrument("TCPIP::192.168.1.105::gpib,5::INSTR")
print(instr.ask("*IDN?"))
# returns 'Agilent Technologies,E3649A,0,1.4-5.0-1.0'

and:

import vxi11
instr = vxi11.Instrument("TCPIP::192.168.1.201::usb0[2391::6056::MY********::0]::INSTR")
print(instr.ask("*IDN?"))
# returns 'AGILENT TECHNOLOGIES,MSO-X 3014A,MY********,02.35.2013061800'
