Connect to the Rigol DP831 in Python

PROTOCOLS > SCPI

import qcodes as qc
from qcodes.instrument_drivers.rigol.DP831 import RigolDP831


# Connect to the power supply
power_supply = RigolDP831('power_supply', 'TCPIP0::192.168.1.1::INSTR')


# Print the power supply's IDN
print(power_supply.IDN())


# Set the voltage of channel 1 to 3.0 V
power_supply.ch1.voltage.set(3.0)


# Set the current limit of channel 2 to 1.5 A
power_supply.ch2.current_limit.set(1.5)


# Enable output on channel 3
power_supply.ch3.output_enable.set(True)


# Disable output on channel 1
power_supply.ch1.output_enable.set(False)


# Close the connection to the power supply
power_supply.close()

Note: Replace 'TCPIP0::192.168.1.1::INSTR' with the actual IP address or VISA resource string of your Rigol DP831 power supply.
