Connecting to Lakeshore Model 372 by Lakeshore in Python

Instrument Card

The Model 372 AC resistance bridge and temperature controller builds on the solid foundation provided by the original Lake Shore AC resistance bridge. The Model 372 provides the best possible temperature measurement and control capabilities for dilution refrigerators (DRs) that are intended to be operated below 100 mK. The Model 372 makes it easy to perform multiple tasks that were once very difficult to perform reliably at ultra-low temperatures:

Connect to the Lakeshore Model 372 in Python

PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

QCodes

To connect to a Lakeshore Model 372 Temperature Controller using Qcodes, you can use the following Python script:

import qcodes as qc
from qcodes.instrument_drivers.Lakeshore.Model_372 import LakeshoreModel372

# Create an instance of the LakeshoreModel372 driver
lakeshore = LakeshoreModel372("lakeshore", "TCPIP::192.168.1.1::7777::SOCKET")

# Connect to the instrument
lakeshore.connect()

# Print the identification string of the instrument
print(lakeshore.IDN())

# Set the setpoint temperature of the sample heater to 300 K
lakeshore.sample_heater.setpoint(300)

# Close the connection to the instrument
lakeshore.disconnect()

In this script, we import the necessary modules and create an instance of the LakeshoreModel372 driver. We provide the name of the instrument and the address (IP address and port number) of the instrument as arguments to the constructor.

We then connect to the instrument using the connect() method. After connecting, we can use the various methods and parameters provided by the driver to interact with the instrument. In this example, we print the identification string of the instrument using the IDN() method and set the setpoint temperature of the sample heater to 300 K using the setpoint() method.

Finally, we disconnect from the instrument using the disconnect() method.

Note: Replace "TCPIP::192.168.1.1::7777::SOCKET" with the actual IP address and port number of your Lakeshore Model 372 Temperature Controller.
