An Introduction to Practical Real-Time Spectrum Analysis Tech Brief Now Available for Download

January 2nd, 2017

cover of intro to spectrum analysis tech brief
Earlier in 2016 we published a series of blog posts introducing real-time spectrum analysis to those who may not fully understand its many concepts. It is a four-part series covering topics such as the basics of spectrum analyzers, channel power, occupied bandwidth, and real-time analysis, amongst others. Last month, we condensed those posts into a […]Read More

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

Blog Series: EMC Precompliance with a Real Time Spectrum Analyzer

EMC Precompliance with Signal Hound Tools
If you’re building electronic hardware or devices intended for public use, you’ll need to pass a certification of some sort that verifies your device is within the electromagnetic interference (EMI) guidelines established by your country. Without this certification your device will legally never make it to market. Electromagnetic compatibility (EMC) is the overarching engineering concerned […]Read More

Practical Real Time Spectrum Analyzer Applications Part 3 — Capturing Digital Signals with RTSAs and Vector Signal Analysis Tools

June 23rd, 2016

Capturing Digital Signals with RTSAs
This is the third and final post in a multi-part blog series where we take a look at a few practical applications of spectrum analyzers. All wireless telecommunication signals undergo modulation in order to impart a data stream within the RF/microwave carrier. Many modern devices rely on digital modulation techniques in order to efficiently transfer […]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
