Connect to the Keysight 34980A in Python

Flojoy

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

Here is a Python script that uses Qcodes to connect to a Keysight 34980A DAQ board:

import qcodes as qc
from qcodes.instrument_drivers.Keysight.Keysight_34980A import Keysight34980A

# Create an instance of the instrument
daq = Keysight34980A('daq', 'TCPIP0::192.168.1.1::INSTR')

# Connect to the instrument
daq.connect()

# Perform operations with the instrument
daq.reset()
status = daq.get_status()
error = daq.get_error()

# Disconnect from the instrument
daq.disconnect()

This script imports the necessary modules and creates an instance of the Keysight34980A instrument with the name ‘daq’ and the specified address. It then connects to the instrument using the connect() method.

After connecting, the script performs some operations with the instrument, such as resetting it, getting the status and error messages. Finally, it disconnects from the instrument using the disconnect() method.
