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 xtralienIf 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)
time.sleep(0.1)
SMU[channel].set.enabled(False, response=0)For more documentation examples see our programming guide.
