Connecting to Keithley 2602B by Keithley in Python

Instrument Card

The 2602B from Keithley is a 2600B series dual channel system SourceMeter® (SMU) instrument (3A DC, 10A pulse). It is an industry’s leading current/voltage source and measure solutions. This dual channel model combines the capabilities of a precision power supply, true current source, 6 1/2 digit DMM, arbitrary waveform generator, pulse generator and electronic load all into one tightly integrated instrument. The result is a powerful solution that significantly boosts productivity in applications ranging from bench-top I-V characterization through highly automated production test. It has 100mV to 40V voltage, 100nA to 10A current measurement range (source). This is tightly integrated, 4-quadrant voltage/current source and measure instrument which offers best in class performance with 6 1/2digit resolution. Built-in web browser based software enables remote control through any browser, on any computer, from anywhere in the world.

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 2602B Power Supply using Qcodes, you can use the following Python script:

from qcodes.instrument_drivers.tektronix.Keithley_2600 import Keithley2602B

# Create an instance of the Keithley2602B instrument
keithley = Keithley2602B('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 Keithley2602B class from the qcodes.instrument_drivers.tektronix.Keithley_2600 module. We then create an instance of the Keithley2602B 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.
