EMC Precompliance with a Real Time Spectrum Analyzer Part 2 — How PC-Driven USB RTSAs Enable Low-Cost And Efficient EMC Precompliance

August 1st, 2016

PC-based EMC Precompliance Testing
This is the second post in a series where we take a look at EMI and EMC precompliance using real time spectrum analyzers. Recent advances in PC-driven USB Real-Time Spectrum Analyzers (RTSAs) have enabled low-cost and efficient EMC precompliance testing and EMI identification with just a few simple tricks. All you would need is an […]Read More

EMC Precompliance with a Real Time Spectrum Analyzer Part 1 — What Is EMC/EMI And EMC Precompliance?

July 22nd, 2016

What Is EMC-EMI And EMC Precompliance
This is the first post in a series where we take a look at EMI and EMC precompliance using real time spectrum analyzers. Virtually every electronic device, and many non-electronic and natural phenomenon, produce electromagnetic radiation. This radiation can, intentionally or otherwise, interfere with proper electronics operation—electromagnetic interference (EMI). Electromagnetic compatibility (EMC) is the study […]Read More

Practical Real Time Spectrum Analyzer Applications Part 2 — RTSA Zero Span Mode For Pulsed Signal Analysis

May 17th, 2016

Zero Span Mode For Pulsed Signal Analysis
This is the second post in a multi-part blog series where we take a look at a few practical applications of spectrum analyzers. Traditional spectrum analysis produces swept plots of power over frequency, revealing the strength of signals caught within the swept device’s analog resolution bandwidth filter. Though valuable for accurately describing continuous wave signals […]Read More

Practical Real Time Spectrum Analyzer Applications Part 1 — Basics Of Interference Hunting And Spectrum Monitoring

May 2nd, 2016

Interference hunting with a Signal Hound spectrum analyzer
This is the first post in a multi-part blog series where we take a look at a few practical applications of spectrum analyzers. There are many cases where accidental or intentional EM interference occurs, which puts even greater burdens on an already crowded spectrum. The ability to capture, analyze, identify, and locate these harmful signals […]Read More

Coming soon! A New Blog Series About Practical Real Time Spectrum Analyzer Applications

April 29th, 2016

spectrum analyzer applications
A few weeks ago we finished up a four-part blog series about the basics of real time spectrum analysis. In the blog series we discussed the basics of how a spectrum analyzer works, why we need them, and the differences between spectrum analysis and real time spectrum analysis, among other things. Armed with this basic […]Read More

What You Need to Know About Real Time Spectrum Analysis

March 23rd, 2016

Real time spectrum analyzer technology
This is the fourth and final post in a multi-part blog series, teaching you the essential concepts of spectrum analysis. With the advent of wide bandwidth analog-to-digital converters (ADCs), high-speed memory, fast processors, and efficient fast-fourier transforms (FFTs), tens to hundreds of megahertz of instantaneous bandwidth can be processed as fast as it is received. […]Read More

What Is Channel Power And Occupied Bandwidth?

March 9th, 2016

This is the third post in a multi-part blog series, teaching you the essential concepts of spectrum analysis. When attempting to analyze or characterize modern telecommunications systems and devices, a spectrum analyzer’s (SAs) ability to measure power over precise sections of spectrum is invaluable. The quality of transmission, nonlinearities, and phase noise of a communication […]Read More

This is the second post in a multi-part blog series, teaching you the essential concepts of spectrum analysis. A measurement on a spectrum analyzer (SA) is taken by configuring, often through software, several key measurement parameters. Many spectrum analyzers have a default setting, along with adjustable center frequency, bandwidth, and power levels. However, not all […]Read More
