Connecting to Keithley 2182 by Keithley in Python

Instrument Card

The two-channel Model 2182A Nanovoltmeter is optimized for making stable, low noise voltage measurements and for characterizing low resistance materials and devices reliably and repeatably. It provides higher measurement speed and significantly better noise performance than alternative low voltage measurement solutions. It offers a simplified delta mode for making resistance measurements in combination with a reversing current source, such as the Model 6220 or 6221.

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.

InstrumentKit

To connect to a Keithley 2182 Power Meter using Instrumentkit, you can use the following Python script:

import instrumentkit as ik

# Connect to the Keithley 2182 Power Meter
meter = ik.keithley.Keithley2182.open_gpibusb("/dev/ttyUSB0", 10)

# Perform a measurement
measurement = meter.measure(meter.Mode.voltage_dc)

# Print the measurement value
print(measurement)

This script imports the instrumentkit module and uses the open_gpibusb method of the Keithley2182 class to connect to the Keithley 2182 Power Meter. The first argument of open_gpibusb is the device path (/dev/ttyUSB0 in this example) and the second argument is the GPIB address (10 in this example).

After connecting to the power meter, the script performs a measurement using the measure method of the Keithley2182 class. The measurement mode is specified as meter.Mode.voltage_dc, which represents the DC voltage measurement mode.

Finally, the script prints the measurement value.
