Connecting to Keysight 33210A by Keysight in Python

Instrument Card

The Keysight (formerly Agilent) 33210A is the latest function/arbitrary waveform generator from Keysight. It uses direct digital synthesis techniques to create a stable, accurate output signal having clean, low distortion sine waves. For user defined waveforms, option 002 provides 14-bit 8k point arbitrary waveform generation

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 33210A Function 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
instrument = WaveformGenerator_33XXX('my_instrument', 'TCPIP0::192.168.1.1::INSTR')

# Connect to the instrument
instrument.connect()

# Now you can use the instrument to control the function generator
# For example, you can set the frequency of channel 1 to 1 kHz
instrument.ch1.frequency(1e3)

# You can also read the current frequency setting
frequency = instrument.ch1.frequency()
print(f"The current frequency is {frequency} Hz")

# Disconnect from the instrument
instrument.disconnect()

This script creates an instance of the WaveformGenerator_33XXX class from the qcodes.instrument_drivers.Keysight.Keysight_33XXX module. It then connects to the instrument using the specified VISA resource address (TCPIP0::192.168.1.1::INSTR in this example).

Once connected, you can use the instrument instance to control the function generator. In the example, it sets the frequency of channel 1 to 1 kHz using the frequency parameter of the ch1 submodule. It then reads the current frequency setting and prints it.

Finally, the script disconnects from the instrument using the disconnect method of the instrument instance.
