New IsoVu™ Isolated Current Shunt Probes Address Neglected Current Ranges Tuesday, November 12, 2024 par : Yogesh Pai

The most common approach to current measurement on oscilloscopes is to use current transformers, Rogowski coils or Hall effect clamp-on probes. High-quality magnetic probes are accurate when used within their specifications. They are also convenient when current is flowing in wires or test loops, since they do not require breaking the circuit. However, they have some intrinsic limitations. In this …

Scope ADC Resolution is Nothing Without Good Probes Thursday, September 19, 2024 par : Andrea Vinci

Key Factors Determining the Accuracy of Electrical Signal Measurement Measurement accuracy is often misunderstood as being solely dependent on the specifications of the instrument, such as the number of waveforms displayed on its screen. However, true accuracy is much more complex. It is closely tied to how well the measurement setup preserves the integrity of the signal being measured. The …

Probe Points: Understanding Low Frequency Response Friday, June 28, 2024 par : Blair Battye

The Practice of AC Coupling and DC Reject Modes The practice of AC coupling the scope input or using a probe with DC reject capability is very common when looking at noise and/or ripple of DC power rails. Anytime there is insufficient DC offset available, then users often elect to use AC Coupling or DC Reject settings. With the focus on clean power, we see users more interested than ever before in …

The Importance of Double Pulse Testing for Designing Today’s Power Converters Thursday, June 27, 2024 par : David Pereles

The field of power electronics is rapidly transitioning from the use of silicon semiconductor materials to wide bandgap semiconductors such as silicon carbide (SiC) and gallium nitride (GaN). One of the most common applications of GaN and SiC semiconductors is to enable smaller, faster and more efficient designs of power converters. Power converters operate at multiple stages throughout the power …

Comment choisir la bonne sonde d'oscilloscope ? Saturday, March 9, 2024 par : Andrea Vinci

Une sonde d'oscilloscope est un appareil qui crée une connexion physique et électrique entre un point test ou une source de signal et un oscilloscope. Selon vos besoins de mesure, cette connexion peut être réalisée avec quelque chose d'aussi simple qu'une longueur de fil électrique ou quelque chose de sophistiqué comme une sonde différentielle active. Une sonde est une sorte de dispositif ou de …

4 Key Testing Phases for Power Conversion Equipment Tuesday, February 14, 2023 par : John Tucker

While the types of electrical tests required during the design and production of power conversion equipment are similar to those required for previous generations of devices, the adoption of wide-bandgap materials like silicon carbide (SiC) or gallium nitride (GaN) requires added rigor and new test strategies. Bench testing continues to play an important role at every stage of the development of …

SiC MOSFETs Represent Opportunities and Measurement Challenges for EV Designers Tuesday, November 15, 2022 par : Christopher Loberg

Innovation in semiconductor technology is enabling more efficient and dense power conversion in hybrid and electric vehicles. Wide bandgap silicon carbide (SiC) technology enables faster switching and lower switching loss in high voltage EV systems. However, the same fast switching and high voltage capabilities that make SiC MOSFETs so promising, also create measurement challenges. Probing the …

New Ways to Access Ever-Smaller DRAM Memory Friday, April 1, 2022 par : Ted Coleman

We’re in a new age of data. As our world becomes more enabled and new technologies are implemented, the world is experiencing an explosion in the amount of data being generated and processed. According to Statista global research, there will be 97 Zettabytes of data created this year. Even more jarring is the acceleration of the pace at which that data is being created; a 2020 study delivered by …
