A library for controlling Ossila's Source Measure Unit

Project description


This module is a simple interface to Ossila's Source Measure Unit.


Xtralien is an open-source project from the Engineers at Ossila to allow control of their equipment easily and Pythonically. It is based on CLOI, the Command Language for Ossila Instruments.


Using pip:

pip install xtralien

If you want to control the equipment using USB you will also need to install pySerial.


Below is a simple example of taking a measurement using the library.

import time

from xtralien import Device

com_port = 'com5'
channel = 'smu1'

# Connect to the Source Measure Unit using USB
with Device(com_port) as SMU:
    # Turn on SMU 1
    SMU[channel].set.enabled(1, response=0)

    # Set voltage, measure voltage and current
    voltage, current = SMU[channel].oneshot(set_v)[0]

    # Print measured voltage and current
    print(f'V: {voltage} V; I: {current} A')

    # Reset output voltage and turn off SMU 1
    SMU[channel].set.voltage(0, response=0)
    SMU[channel].set.enabled(False, response=0)
