Capture Elusive RF Signals with Advanced Software for Handheld Spectrum Analyzers Tuesday, November 26, 2024
RF signals are more dynamic and unpredictable than ever, which presents new challenges for engineers. Even traditional vector spectrum analyzers struggle to capture transient or intermittent signals, leaving you without a complete picture of how your circuit or system is performing. Tektronix SignalVu-PC software now provides three advanced triggers enabling you to visualize, capture, and analyze …

Achieve Fine Control of Pulsed Lasers with High-bandwidth Arbitrary Waveform Generators Friday, November 17, 2023
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 …

Separating RSA Facts from RSA Fiction Wednesday, July 5, 2023
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 …

The Need for Fully Configurable, Multi-Channel RF Analysis Tuesday, March 28, 2023
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 …

4 Methods for Measuring Pulse Modulations in Radar Signals Friday, January 20, 2023
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 …

Spectrograms show spectral activity over time with amplitude indicated by color
Spectrogram Types: The Many Faces of the Spectrogram Tuesday, November 15, 2022
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 …

Building Your Own EMI Troubleshooting and Pre-Compliance Kit Monday, October 17, 2022
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 …

Overcoming 3 Challenges of Time and Frequency Correlated RF Measurements Thursday, June 16, 2022
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 …
