Woman using a Tektronix IsoVu Isolated Current Shunt Probe and 4 Series B MSO oscilloscope to measure dynamic draw on a processor board during I/O activity.

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 …

Engineer using a 4 Series B MSO oscilloscope with motor drive analysis software to analyze the 3-phase output of a motor drive used in an electric vehicle

Bringing More Power Analysis Tools to Engineers’ Benches with the 4 Series B MSO Thursday, July 18, 2024 par : David Pereles

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 …

Low frequency response curves with AC coupling or DC reject turned on, for different types of probes

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 …

Tektronix’ Wide Bandgap Double Pulse Test Solution including the Wide Bandgap Double Pulse Test application (Opt. WBG-DPT) which runs on the 5 Series B MSO oscilloscope

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 …

3 Things to Consider When Synchronizing Oscilloscopes for Higher Channel Count Tuesday, January 16, 2024 par : Tektronix Expert

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 …

MIMO Radar System Testing Tools and Techniques Thursday, January 11, 2024 par : Dylan Stinson

Modern technologies such as MIMO require the need for wide bandwidth, phase coherent, multi-channel analysis. Antenna elements in a MIMO radar system operate independently to cover a wide, often 180-degree, field of view without the need for directivity adjustments. This significantly improves scan times. The MIMO radar employs time, frequency, or coding techniques in each transmit signal to …
