Connecting to Keithley 2600 by Keithley in Python

Instrument Card

Series 2600A System SourceMeter instruments are Keithley’s latest I-V source measurement unit (SMU) instruments for use as either bench-top I-V characterization tools or as building block components of multi-channel I-V test systems. For bench-top use, Series 2600A instruments feature an embedded TSP Express Software Tool that allows users to quickly and easily perform common I-V tests without programming or installing software. For system level applications, the Series 2600A’s Test Script Processor (TSP) architecture, along with other new capabilities such as parallel test execution and precision timing, provides the highest throughput in the industry, lowering the cost of test. To simplify the testing, verification, and analysis of semiconductor components, the optional ACS Basic Edition software is also available.

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.

PyMeasure

Here is a Python script that uses Pymeasure to connect to a Keithley 2600 Power Supply:

from pymeasure.adapters import VISAAdapter
from pymeasure.instruments.keithley import Keithley2600

# Create a VISA adapter for communication
adapter = VISAAdapter("TCPIP::192.168.1.1::INSTR")

# Connect to the Keithley 2600 Power Supply
keithley = Keithley2600(adapter)

# Set the source mode to voltage and apply a voltage of 5V
keithley.ChA.source_mode = 'voltage'
keithley.ChA.source_voltage = 5.0

# Enable the output
keithley.ChA.source_output = 'ON'

# Measure the voltage and current
voltage = keithley.ChA.voltage
current = keithley.ChA.current

# Print the measured values
print("Voltage: %.3f V" % voltage)
print("Current: %.3f A" % current)

# Disable the output and close the connection
keithley.ChA.source_output = 'OFF'
# Disconnect from the Keithley 2600 Power Supply
keithley.disconnect()

This script connects to a Keithley 2600 Power Supply using a VISA adapter. It sets the source mode to voltage and applies a voltage of 5V to channel A. Then, it enables the output and measures the voltage and current. Finally, it disables the output and closes the connection.
