QCodes Community

To connect to a Rohde & Schwarz HMP4030 Power Supply using Qcodes Community, you can use the following Python script:

from qcodes.instrument_drivers.rohde_schwarz.HMP4030 import RohdeSchwarzHMP4030

# Create an instance of the HMP4030 driver
hmp = RohdeSchwarzHMP4030('hmp', 'TCPIP0::192.168.0.1::INSTR')

# Connect to the instrument
hmp.connect()

# Now you can use the instrument for various operations
# For example, you can set the output voltage
hmp.voltage(5)  # Set the output voltage to 5V

# You can also read the current output voltage
voltage = hmp.voltage()
print(f"Output voltage: {voltage}V")

# Disconnect from the instrument
hmp.disconnect()

In this script, we import the RohdeSchwarzHMP4030 class from the qcodes.instrument_drivers.rohde_schwarz.HMP4030 module. We then create an instance of the driver by providing a name for the instrument ('hmp') and the instrument’s address ('TCPIP0::192.168.0.1::INSTR').

Next, we connect to the instrument using the connect() method. After connecting, we can perform various operations on the instrument. In this example, we set the output voltage to 5V using the voltage() method and then read the current output voltage using the same method.

Finally, we disconnect from the instrument using the disconnect() method.
