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 …

Separating RSA Facts from RSA Fiction Wednesday, July 5, 2023 par : Alejandro Buritica

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 …

Spectrograms show spectral activity over time with amplitude indicated by color

Spectrogram Types: The Many Faces of the Spectrogram Tuesday, November 15, 2022 par : Alan Wolke

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 …

Are You Keeping Pace with Wide-Bandgap Test Requirements? Tuesday, September 13, 2022 par : Tektronix Expert

A new generation of wide-bandgap (WBG) materials such as silicon carbide (SiC) and gallium nitride (GaN) are becoming more prevalent. Electrically, these substances are closer to insulators than silicon and other typical semiconductor materials. Their adoption is an effort to overcome limitations of silicon that stem from it being a narrow bandgap material, which leads to undesirable conductive …

Overcoming 3 Challenges of Time and Frequency Correlated RF Measurements Thursday, June 16, 2022 par : Tektronix Expert

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 …

Spectrum View: A New Way of Analyzing Signals Across Multiple Domains Tuesday, December 14, 2021 par : Brandon Gould

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 …

How to Use Spectrum View for Easier, More Accurate Insights Tuesday, December 14, 2021 par : Brandon Gould

Efficient system analysis and debug relies on insights but correlating signals across multiple domains has traditionally been a painful, technically challenging process. It can be difficult to figure out why a system isn’t working as expected without precise, synchronized insight into both time and frequency domains. Spectrum View was created to solve that challenge. The 4, 5 and 6 Series MSO …

3 Radiation Hazards (RADHAZ) and How to Mitigate Risk Wednesday, September 8, 2021 par : Tektronix Expert

If you are involved in military, aerospace or defense and have been around radar and communication systems, with high-power RF transmitters and high-gain antennas, you are probably aware of the many risks associated with Radio Frequency Radiation (RFR) Hazards. RF emissions from these systems have the potential to cause catastrophic damage to operations and maintenance personnel, ordnance and …

Monitoring the wireless spectrum for interference

3 System Design Challenges with Spectrum Monitoring Tuesday, September 7, 2021 par : Tektronix Expert

The wireless spectrum is a finite commodity that is tightly regulated, managed and shared by all nations, manufacturers and citizens, who risk being fined if they are caught operating outside of what's regulated or licensed. The presence of interference or other signals of interest creeping into one's band of wireless spectrum is a daily occurrence to some and is of great concern to many who may …
