Connecting to Lakeshore 370 by Lakeshore in Python

Instrument Card

The Model 370 AC resistance bridge is designed for precise, accurate, low noise, low excitation power AC resistance measurements. Its primary application is the measurement of resistive materials in cryogenic environments from 20 mK to 1 K. Fully integrated, the Model 370 includes features to reduce and control noise at every step of the resistance measurement process. A unique, patented, matched impedance current source and active common mode reduction circuitry minimize noise and self-heating errors. With up to 16 channels, IEEE-488 and serial interfaces, and closed loop temperature control, the Model 370 offers seamless integration with existing cryogenic systems and is the most complete package on the market today. Used with Lake Shore calibrated subkelvin resistance temperature sensors, it not only measures and displays, but also controls temperature for dilution refrigerators and other cryogenic systems.

Connect to the Lakeshore 370 in Python

PROTOCOLS > SCPI

To connect to a Lakeshore 370 AC resistance bridge using Instrumentkit, you can use the following Python script:

import instrumentkit as ik


# Connect to the Lakeshore 370 AC resistance bridge
bridge = ik.lakeshore.Lakeshore370.open_gpibusb('/dev/ttyUSB0', 1)


# Query the resistance of the first channel
resistance = bridge.channel[0].resistance


# Print the resistance value
print(resistance)

This script imports the instrumentkit module and uses the open_gpibusb method of the Lakeshore370 class to connect to the Lakeshore 370 AC resistance bridge. The open_gpibusb method takes the device path ('/dev/ttyUSB0') and the GPIB address (1) as arguments.

After connecting to the bridge, the script queries the resistance of the first channel using the resistance property of the Channel class. Finally, it prints the resistance value.

Note: Make sure to install the instrumentkit package before running this script.
