Connecting to Rigol DP8xx-Series by Rigol in Python

Instrument Card

The DP800 Series Power Supplies combine the ability to source, analyze, and coordinate over time on a powerful platform. The DP800 Series is a family of linear power supplies systems with 1, 2, or 3 outputs and 140 to 200 Watts in total. With one channel isolated users can reconfigure instruments into any number of systems or applications. Built in V, A, and W measurements make power monitoring easy, but additional wave tracking, timing, and analysis features in the advanced “A” models means there are even more ways to use the instruments. Digital triggering between instruments also makes it possible to reliably combine and connect supplies together. Intuitive to use for everything from education labs to the R & D bench, the DP800 family of power supplies provide incredible value for any application. Select the value models for best price performance or upgrade to the “A” model to improve resolution and add advanced monitoring, triggering, and programming capabilities.

Connect to the Rigol DP8xx-Series 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

Here’s an example Python script that uses Qcodes to connect to a Rigol DP8xx-Series Power Supply:

from qcodes.instrument_drivers.rigol.DP8xx import DP832

# Create an instance of the DP832 power supply
power_supply = DP832("power_supply", "USB0::0x1AB1::0x0E11::DP8C203600050::INSTR")

# Connect to the power supply
power_supply.connect()

# Print the installed options
print(power_supply.installed_options())

# Set the voltage and current for channel 1
power_supply.ch1.set_voltage(3.0)
power_supply.ch1.set_current(1.0)

# Enable the output for channel 1
power_supply.ch1.state(True)

# Read the measured voltage and current for channel 1
voltage = power_supply.ch1.voltage()
current = power_supply.ch1.current()

# Print the measured voltage and current
print(f"Measured Voltage: {voltage} V")
print(f"Measured Current: {current} A")

# Disconnect from the power supply
power_supply.disconnect()

This script creates an instance of the DP832 class from the qcodes.instrument_drivers.rigol.DP8xx module. It then connects to the power supply using the specified address (in this case, a USB connection). The installed options are printed using the installed_options() method.

The voltage and current for channel 1 are set using the set_voltage() and set_current() methods. The output for channel 1 is enabled using the state() method.

The measured voltage and current for channel 1 are read using the voltage() and current() methods. The values are then printed.

Finally, the script disconnects from the power supply using the disconnect() method.
