VESA Mount Arm For Rigol DHO800 Series | Voltlog #474

Elevate your workbench ergonomics with a simple yet ingenious solution – mounting your Rigol DHO800 oscilloscope on an articulated monitor arm. In this innovative setup, I’ll guide you through the process of maximizing your workspace while improving your workflow efficiency. The key to this hack lies in the Rigol DHO800’s standard VESA mount, allowing you to seamlessly integrate it with a monitor arm.

Imagine having your oscilloscope swing in and out of your work area effortlessly, freeing up valuable bench space for other tools and projects. No more awkward positioning or constant rearranging – just a clean, organized setup tailored to your needs. Choosing the right monitor arm is crucial. While high-end options with gas struts and multiple articulating points exist, a simple, spring-based arm like the Maclean MC-458 can be a cost-effective solution.

At just $30, it offers a weight range of up to 7kg, perfect for the lightweight Rigol DHO800 (approximately 1.5kg). If your oscilloscope is too light for the arm’s tension, a clever hack is to add artificial weight using wheel weights from a tire shop. Simply attach them to the VESA mount, and voilà – your oscilloscope will balance perfectly with the arm’s force.

Integrating the monitor arm into an aluminum profile workbench is a breeze, thanks to the standard channel spring nuts and M8 bolts. Adjust the height, angle, and rotation to suit your preferences, and enjoy a truly ergonomic viewing experience.

The New Rigol DHO800 Series Review | Voltlog #469

The wait is finally over for Rigol enthusiasts! After eight long years, the renowned oscilloscope brand has unveiled the highly anticipated DHO800 series, a remarkable upgrade to the beloved DS1054Z. As a proud owner of the latter, I was thrilled to get my hands on the top-of-the-line DHO814 model, courtesy of Eleshop.eu and Rigol.

Straight out of the box, the DHO814 exudes an air of modernity and refinement. Its compact, featherweight form factor is a stark contrast to its robust predecessor, promising to save precious real estate on your workbench. The glossy, 7-inch capacitive touchscreen with a resolution of 1024×600 pixels adds a touch of elegance, while the familiar array of buttons and knobs ensures a seamless transition for seasoned users.

Under the hood, the DHO814 packs a punch with an array of impressive upgrades. The bandwidth now starts at a respectable 70MHz, with the top-tier model boasting a 100MHz capability. The sampling rate has received a modest boost to 1.25GS/s, while the vertical resolution has undergone a game-changing leap to 12 bits, promising unparalleled signal capture and visualization.

One of the standout features is the UltraAcquire mode, which enables a staggering waveform capture rate of up to 1 million waveforms per second, ensuring you never miss a transient event. The memory depth has also increased to 25Mpts, providing ample headroom for intricate signal analysis.

Voltlog #250 – Replacing Bad 4mm Banana Plugs With High Quality Hirschmann and Staubli

In this video I replace some of my old crappy 4mm banana connectors with some new Hirschmann and Staubli, high quality connectors. These should be more reliable and provide a low resistance connection between my test gear allowing me to pass high currents without any issue.
