Is the UNI-T UDP3305S the BEST Programmable Power Supply? Find Out! | Voltlog #478

Are you tired of juggling multiple power supplies on your workbench? The UNI-T UDP3305S could be the solution you’ve been waiting for. This programmable DC power supply unit combines four independent channels into one sleek and powerful package, making your life easier and more productive. With three independently programmable outputs (two at 0-30V 5A and one at 0-6V 3A) and a fixed 5V 2A USB output, the UDP3305S offers a total combined power output of 348W.

Its 1mV/1mA resolution and low ripple voltage of less than 350uV (measured at 1MHz bandwidth) make it suitable for powering even the most sensitive analog circuits. One of the standout features of this unit is its ability to internally switch channels 1 and 2 to series or parallel mode, eliminating the need for external wiring and separate adjustments.

Need more than 30V? Switch to series mode for up to 60V at 5A. Need more current? Parallel mode delivers 30V at 10A. The 4.3-inch TFT display provides a clear and intuitive graphical user interface, allowing you to monitor and adjust settings with ease. The unit also offers advanced features like waveform viewing, programmable sequences, monitoring, triggering, and data logging.

With a robust build quality, rubber corner protection, and a carry handle, the UDP3305S is designed for the demanding workbench environment. Connectivity options include USB, Ethernet, RS232, and digital I/O, enabling remote control and integration into automated test setups. While the included Windows software could be more polished, the instrument itself excels in usability and performance.

Compared to alternatives from Rigol, Siglent, and others, the UNI-T UDP3305S offers more features at a lower cost, making it an attractive choice for professionals and hobbyists alike.

Adding WiFi Connection To Rigol DHO800 Series | Voltlog #470

Unleash the Full Potential of Your Rigol DHO800 Series Oscilloscope with this Simple WiFi Hack! If you’ve been frustrated by the lack of built-in WiFi connectivity on your Rigol DHO800 series oscilloscope, fear not! Thanks to the ingenuity of the eevblog forum community, there’s a straightforward solution that will allow you to add wireless connectivity to your device with minimal effort.

The key to this hack lies in the Android operating system running underneath the Rigol DHO800 series oscilloscopes. By leveraging the pre-installed drivers for the Realtek RTL8188 chipset, you can transform your oscilloscope into a WiFi-enabled powerhouse with just a simple USB WiFi adapter. To accomplish this, you’ll need to acquire a TP-Link TL-WN725N USB WiFi Adapter (version 2 or 3), which is widely available and affordable.

These adapters are specifically designed with the Realtek RTL8188 chipset, ensuring seamless compatibility with the Android drivers on your oscilloscope. Once you have the adapter, simply connect it to your oscilloscope using a USB hub (along with a keyboard for initial setup), and follow the step-by-step guide provided in the video.

By accessing the Android operating system’s settings through keyboard shortcuts, you can easily connect to your desired WiFi network and enjoy wireless connectivity. While this hack may not be officially supported by Rigol and may exhibit some quirks (such as the GUI showing “network disconnected” despite being connected), the benefits far outweigh the minor inconveniences.

With WiFi connectivity, you can access the oscilloscope’s web control interface, transfer screenshots seamlessly, and even adjust the display brightness – a feature previously unavailable through the GUI.
