QCodes

To connect to a Weinschel 8320 Digital Attenuator using Qcodes, you can use the following Python script:

from qcodes.instrument.visa import VisaInstrument

# Create an instance of the Weinschel8320 instrument
weinschel = Weinschel8320('weinschel', 'your_visa_address')

# Connect to the instrument
weinschel.connect()

# Set the attenuation to 10 dB
weinschel.attenuation(10)

# Get the current attenuation value
attenuation_value = weinschel.attenuation()

# Print the current attenuation value
print(f"Current attenuation: {attenuation_value} dB")

# Disconnect from the instrument
weinschel.disconnect()

Make sure to replace 'your_visa_address' with the actual VISA address of your Weinschel 8320 Digital Attenuator.
