Connecting to Keysight 33250A by Keysight in Python

Instrument Card

The 33250A 80 MHz Function/Arbitrary Waveform Generator uses direct digital-synthesis techniques to create a stable, accurate output on all waveforms, down to 1 µHz frequency resolution. The benefits are apparent in every signal you produce, from the sine wave frequency accuracy to the fast rise/fall times of square waves, to the ramp linearity.

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 Keysight 33250A RF Signal Generator using Qcodes, you can use the following Python script:

from qcodes.instrument_drivers.Keysight.Keysight_33XXX import WaveformGenerator_33XXX

# Create an instance of the instrument
signal_generator = WaveformGenerator_33XXX('signal_generator', 'TCPIP0::192.168.1.1::INSTR')

# Connect to the instrument
signal_generator.connect_message()

This script imports the WaveformGenerator_33XXX class from the qcodes.instrument_drivers.Keysight.Keysight_33XXX module. It then creates an instance of the instrument with the name “signal_generator” and the appropriate VISA address for your specific instrument. Finally, it calls the connect_message() method to establish a connection to the instrument and print a connection message.
