PROTOCOLS > SCPI

from qcodes import create, VisaInstrument


# Create an instance of the ILM 200 Power Meter
ilm = create('ilm', 'OxfordInstruments_ILM200', address='ASRL4::INSTR')


# Get the helium level
level = ilm.level()


# Get the status of the device
status = ilm.status()


# Set the probe rate to fast
ilm.rate(1)


# Close the connection
ilm.close()

Explanation:

  1. Import the necessary modules and classes from Qcodes.
  2. Create an instance of the OxfordInstruments_ILM200 class using the create function. Provide a name for the instrument (ilm) and the instrument address (ASRL4::INSTR).
