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

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

What You Need to Know About Real Time Spectrum Analysis

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
