High-speed pulse testing is at the forefront of modern research, playing a critical role in areas such as Photonic Doppler Velocimetry (PDV) and Broadband Laser Ranging (BLR) used in high energy physics exploration. The ability to accurately capture and analyze events that occur in microseconds or even nanoseconds is paramount, and the precision required is exceptionally demanding. Even minor …
Have you ever wished that pulling waveform data from your oscilloscope could be faster? In this blog, we’ll explore TekHSI (Tektronix High Speed Interface), the speed improvements it offers, and review examples on why it’s so easy to use.
What is TekHSI?
TekHSI is a new feature available on Tektronix 4B, 5 and 6 (B and LP) Series MSO Oscilloscopes via the latest firmware update, v2.10. TekHSI is …
High-Quality Education with High-Quality Scopes
In classrooms around the world, oscilloscopes are a gateway to understanding the invisible world of signals and circuits. But for many students, the excitement of discovery often gives way to frustration as they wrestle with complex controls and unfamiliar interfaces. Students and instructors often waste precious lab time figuring out how to use …
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 …
It can be challenging to consistently measure the performance of AC-DC and DC-DC converters. These challenges have become even greater as designers work to transition from silicon-based power converters to wide bandgap semiconductors such as silicon carbide (SiC) and gallium nitride (GaN). Designers of 3-phase systems such as motor drives face additional complexity.
Thankfully, help is available …
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 …
As electric vehicles (EVs) continue to proliferate, understanding the infrastructure that supports them, particularly Electric Vehicle Supply Equipment (EVSE), or charging stations, becomes crucial. This guide explains what EVSE is, how it works, and why it's essential for the transition to electric mobility.
After learning about EVSE, take the next step to learn about EVSE test and measurement …
When constructing a test system, there might be a need to measure more signals than a single oscilloscope can capture with its available channels. To increase the number of oscilloscope channels in a test system, a common approach is to combine multiple oscilloscopes. Multi-channel measurements find application in various scenarios, such as capturing complex particle physics experiments, measuring …
