Fine-tuning your Emergency Communications Setup and Knowledge with Commsprepper

YouTube publisher Commsprepper knows his stuff when it comes to emergency communications. One glance at his list of videos reveals a guy who is not only varied in his knowledge of wireless field operations, but also extremely passionate. Amateur radio enthusiasts are a large subset of Commsprepper’s followers, and for good reason. While the spin

EMC Precompliance with a Real Time Spectrum Analyzer Part 1 — 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

Practical Real Time Spectrum Analyzer Applications Part 2 — RTSA 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

What You Need to Know About Real Time Spectrum Analysis

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.

What Is Channel Power And Occupied Bandwidth?

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

Spectrum Analyzer Basics

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
