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 …
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 …
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 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 …
Introduction
Deployment of AI-based technology is happening in the Data Center. The processor-intensive servers are driving up energy demands. The table below illustrates the magnitude of the impact. The International Energy Agency (IEA) predicts that data centers will account for up to seven percent of global electricity consumption by 2030; a number equivalent to the entire country of India’s …
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 …

Deep Dive Into DDR5 and LPDDR5/5X
Explore the Tektronix memory solutions (leveraging powerful analysis tools) on AMD’s …
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 …
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 …
In this article, we will explore in detail some best practices to follow when handling Tektronix's isolated differential probe, also known as IsoVu™ probes.
What is IsoVu?
IsoVu is the brand name used to describe Tektronix's isolated differential probes. Generation One (TIVHx/TIVMx) was released several years ago, and Generation Two (TIVPx) came out more recently. IsoVu probes were originally …
