High-power pulsed lasers drive many science and engineering experiments in spectroscopy, metrology, quantum information, atomic physics, and materials research. To perform these experiments reliably and consistently, researchers need to control pulsed lasers with high accuracy, great flexibility, and tight timing. This is where Tektronix arbitrary waveform generators (AWGs) with high sampling …
Researchers, engineers, and technicians working on RF applications generally have a good grasp on the use and benefits of spectrum analyzers, whether they are traditional swept spectrum analyzers (TSA) or more modern vector signal analyzers (VSA). They understand the key specifications and principles of operation of these important RF instruments. However, sometimes they are puzzled by a slightly …
Engineers and researchers whose work involves MIMO, phased array, and beam forming need a signal analysis tool that offers wide bandwidth and multi-channel capability. Oscilloscopes would seem to be a good choice – except many are either not designed to analyze RF signals or are limited to analyzing a single RF channel at a time.
But RF spectral and modulation analysis of multiple channels …
Modern radar signals make use of intra-pulse modulation or modulation on pulse (MOP), such as a linear frequency modulation (LFM), or some form of phase modulation (such as a bi-phase Barker code) to improve range resolution. They also include modulation on pulse to occupy more bandwidth and thus decrease the probability of intercept (POI). Additionally, intra-pulse modulation can include some …
Tektronix RF Product Manager, Alejandro Buritica, recently penned an article for Microwaves & RF titled Improve the Reliability of 6G Designs with High-Fidelity Test Beds. In it he discusses the early-stage challenges with 6G, including how the lofty expectations are challenging test and measurement engineers, how to analyze signal quality, and how to increase design reliability.
6G will demand …
What is a Spectrogram
A spectrogram is a graphic that shows the viewer how the frequency domain content (spectral content) of a signal or signals is changing or progressing over time. It consists of a collection of spectrum traces that are collected/processed over time and stacked next to each other, much like slices of bread in a loaf. While each individual spectrum trace would be on the “butter …
Dylan Stinson, Product Marketing Manager at Tektronix, recently penned an article for the Interference Technology’s 2022 EMC Testing Guide: How to Build Your Own EMI Troubleshooting and Pre-Compliance Kit. We wanted to share some of the key insights here.
Failing EMI/EMC compliance testing can certainly ruin a design engineer’s day. The costs and time delays associated with a failed test can add …
Historically, engineers working with high-frequency signals have relied on spectrum analyzers to identify, characterize, and test the performance of their designs, devices, and systems. But these devices fall short when analyzing signals with an unpredictable time-related behavioral component.
Tektronix Real-Time Spectrum Analyzers (RTSAs), however, capture and store signals as a seamless …
Customer-Driven Improvements in the New 5 Series B MSO Deliver an Even Better User Experience and More Capabilities
Oscilloscopes are among the most important tools in the electronics industry. So, it’s not surprising that the choice of a specific oscilloscope by an engineer can be a deeply personal matter. And engineers, by their nature, are full of ideas for improvement. Since the release of …
Analyzing Signals Across Multiple Domains
There is increasing interference in the RF domain as we work to make IoT devices more powerful, consume less energy and have longer battery lives but still broadcast high-quality RF communication. From smart watches to heart rate sensors, the devices being designed today are getting smaller and smaller, which makes signal integrity more important than ever …
