Connecting to Rigol DP831 by Rigol in Python

Instrument Card

The Rigol DP831 features a relative large (8.9 cm / 3.5”) and easy to read TFT monochrome display. In addition to the normal digital displays for voltage, current, and power, these values can also be displayed as signal curves.

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

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.
