How to Work Safely With High-Voltage Test and Measurement Equipment

When working with high-voltage test and measurement equipment, electrical and test engineers strive to achieve the most precise readings possible while also maintaining a safe work area. Typically, they employ external probes such as high-voltage dividers, but these instruments come with drawbacks and are prone to errors.

9 Steps to Select a Test Cable for Millimeter Wave Applications

Radio signal frequencies are rising to the millimeter-wave (mmWave) range as applications such as 5G networks and automotive radar systems seek more bandwidth at higher frequencies. Testing is an important part of producing new products at mmWave frequencies and coaxial cable assemblies are vital parts in getting signals from a signal generator to a device under test (DUT) and then to an analyzer.

Evaluation of Intelligent and Non‑Static Power Sources: A Rational Clarification

Product standards, such as IEC 62368‑1 for ITC equipment, struggle to keep up with technology changes, even when they are designed to be adaptable – such as this hazard-based standard. Unexpected consequences can develop with the introduction of disruptive technology that takes advantage of a seeming loophole in a standard and move forward without getting a full evaluation under the standard. Fault managed power systems, such as PoE, push the standard in getting proper evaluation. This paper is a case study including a detailed proposal as to how to address an issue such as this within the standard.

Why Histograms and Free Run Matter

Oscilloscopes are key tools for power integrity measurements. With decreasing DC voltages and tolerances, techniques for accurate power rail testing have to be refined constantly. This article presents a new, widely unknown approach which reduces test times significantly. It combines waveform histograms and free run trigger mode, which lets developers capture and analyze a much higher percentage of rail activity than the traditional method.
