Connect to the Rigol DP832 in Python

Read our guide for turning Python scripts into Flojoy nodes.

Flojoy

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 a Rigol DP832 Power Supply using Qcodes, you can use the following Python script:

from qcodes.instrument_drivers.rigol.DP8xx import RigolDP832

# Create an instance of the RigolDP832 driver
power_supply = RigolDP832('power_supply', 'TCPIP0::192.168.1.1::INSTR')

# Connect to the power supply
power_supply.connect()

# Now you can use the power supply to perform various operations
# For example, to set the voltage of channel 1 to 5V:
power_supply.ch1.voltage.set(5)

# To turn on channel 2:
power_supply.ch2.output.set(True)

# To read the current of channel 3:
current = power_supply.ch3.current.get()

# Disconnect from the power supply
power_supply.disconnect()

Note: Replace 'TCPIP0::192.168.1.1::INSTR' with the actual IP address or VISA resource string of your Rigol DP832 Power Supply.
