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
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
​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
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 …
Wideband Oscilloscopes for MIMO radar testing being used by and engineer.
MIMO Radar System Testing Tools and Techniques Thursday, January 11, 2024
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 …
Tektronix 475A Analog Oscilloscope
What is an Analog Oscilloscope? Wednesday, December 6, 2023
Introduction Imagine diagnosing complex electronic issues with a tool that has stood the test of time: the analog oscilloscope. This article takes you through the journey of this indispensable instrument, from its historical roots to modern applications. Although Analog Oscilloscopes are no longer manufactured, our Digital Oscilloscopes can read Analog signals. View Digital Oscilloscopes …
Jeffrey Miller, Tektronix Product Manager, poses with the new 4 Series B MSO.
What Is New in the 4 Series B MSO Wednesday, December 6, 2023
The 4 Series MSO introduced a new approach to 4-class mixed signal oscilloscopes when it first released in 2019. With its innovative made-for-touch user interface and high-definition display, it brought the user experience of the acclaimed 5 Series MSO to a broader audience and with a smaller bench footprint. The 4 Series won an Electronics Products Product of the Year award in that same year, and …
PCI Express 128GT/s PAM4 Eye
Where Are We Going after PCIe 6? Tuesday, October 10, 2023
The physical layer of PCIe Express® has rapidly evolved from Gen 4.0 to Gen 5.0 and finally to Gen 6.0 with a 6.0 spec that describes everything that's necessary to develop silicon. We’ve gone from 16 to 32 and for Gen 6.0 up to 64 GT/s (Giga-transfers per second). And for the first time, we've gone to PAM4 multi-level signaling that allows us to encode two bits of information into a single unit …
Alignment waveform used to find and remove skew for double pulse testing
A New Software Deskew Approach Accelerates Double Pulse Testing Tuesday, September 12, 2023
Accurate energy loss measurements are one of the key objectives of double pulse testing. Eliminating the timing skew between voltage and current probes is a critical step in making accurate power and energy measurements on an oscilloscope. The double pulse testing software (WBG-DPT), available on the 4 Series, 5 Series and 6 Series MSOs, includes a new deskew technology designed specifically for …
