Connecting to Keithley 2604B by Keithley in Python

Instrument Card

The 2604B SourceMeter SMU instrument is a new dual channel SMU instrument with best-in-class value and performance. Its tightly integrated four-quadrant design allows it to simultaneously source and measure both voltage and current to boost productivity in R&D and bench-top applications. The Model 2604B is equipped with our high speed TSP technology, which is over 190% faster than traditional PC-to-instrument communication techniques. The Model 2604B is designed for bench-top applications and, therefore, does not have the high-end, system-level automation features of the Model 2602B SourceMeter SMU Instrument that includes digital I/O, TSP-Link technology, and contact check function. The wide range of 3A DC, 10A pulse, 40V output makes the Model 2604B suitable for testing a wide range of higher current devices, materials, components, and sub-assemblies.

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 Keithley 2604B Power Supply using Qcodes, you can use the following Python script:

from qcodes.instrument_drivers.tektronix.Keithley_2600 import Keithley2604B

# Create an instance of the Keithley2604B instrument
keithley = Keithley2604B('keithley', 'TCPIP::192.168.1.1::INSTR')

# Connect to the instrument
keithley.connect()

# Perform operations with the instrument

# Disconnect from the instrument
keithley.disconnect()

In this script, we import the Keithley2604B class from the qcodes.instrument_drivers.tektronix.Keithley_2600 module. We then create an instance of the Keithley2604B instrument, providing a name for the instrument (‘keithley’) and the connection string (‘TCPIP::192.168.1.1::INSTR’).

Next, we connect to the instrument using the connect() method. You can perform various operations with the instrument, such as setting voltage or current, measuring voltage or current, etc.

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

Note: Make sure to replace the connection string (‘TCPIP0::192.168.1.1::inst0::INSTR’) with the appropriate IP address or other connection details for your specific setup.
