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

import qcodes as qc
from qcodes.instrument_drivers.Keysight.Keysight_344xxA import Keysight34461A

# Create an instance of the Keysight34461A driver
dmm = Keysight34461A('dmm', 'TCPIP0::192.168.1.1::INSTR')

# Connect to the instrument
dmm.connect()

# Perform measurements or other operations with the instrument

# Disconnect from the instrument
dmm.disconnect()

Explanation:

1. Import the necessary modules: qcodes and the Keysight34461A driver from qcodes.instrument_drivers.Keysight.Keysight_344xxA.
2. Create an instance of the Keysight34461A driver with a name (‘dmm’) and the instrument’s address (‘TCPIP0::192.168.1.1::INSTR’).
3. Connect to the instrument using the connect() method.
4. Perform measurements or other operations with the instrument.
5. Disconnect from the instrument using the disconnect() method.
