Introduction

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

Requirements

  • Python 2 or Python 3

Installation

Extract and run

# python setup.py install

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'
