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 an AMI 430 Power Supply using Qcodes, you can use the following code:

from qcodes.instrument_drivers.american_magnetics.AMI430 import AMI430

# Create an instance of the AMI430 instrument
ami430 = AMI430("ami430", "TCPIP::192.168.1.1::7180::SOCKET")

# Connect to the instrument
ami430.connect()

# Now you can use the instrument to control the power supply
# For example, you can set the field to a specific value
ami430.field(0.5)  # Set the field to 0.5 Tesla

# You can also read the current field value
field = ami430.field()
print("Current field:", field)

# When you are done, remember to disconnect from the instrument
ami430.disconnect()

Make sure to replace "TCPIP::192.168.1.1::7180::SOCKET" with the actual IP address and port of your AMI 430 Power Supply.
