Connecting to HDAWG by Zurich Instruments in Python

Instrument Card

The Zurich Instruments HDAWG multi-channel Arbitrary Waveform Generator has one of the highest channel densities available in its class and is designed for advanced signal generation up to 750 MHz bandwidth. The HDAWG comes with either 4 or 8 DC-coupled, single-ended analog output channels with 16-bit vertical resolution.

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 Community

To connect to a HDAWG RF Signal Generator using Qcodes Community, you can use the following Python script:

from qcodes import Station, Instrument
from qcodes.instrument_drivers.zhinst import ZIHDAWG8

# Create a station to hold the instrument
station = Station()

# Connect to the HDAWG RF Signal Generator
hdawg = ZIHDAWG8('hdawg', 'dev1234')

# Add the instrument to the station
station.add_component(hdawg)

# Now you can use the instrument to perform operations
hdawg.enable_channel(1)
hdawg.start_awg(1)

# Disconnect from the instrument
hdawg.close()

In this script, we first import the necessary modules and classes from Qcodes. Then, we create a Station object to hold the instrument. Next, we create an instance of the ZIHDAWG8 class, passing the name of the instrument (‘hdawg’) and the device ID (‘dev1234’) as arguments. We add the instrument to the station using the add_component method. Finally, we can use the instrument to perform operations such as enabling a channel and starting the AWG. Note: Replace 'dev1234' with the actual device ID of your HDAWG RF Signal Generator.
