Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...

This document provides step-by-step instructions on using the Rigol DSA-800 series of Spectrum Analyzers to measure the characteristics of an RF Amplifier. In addition to the DSA-800 Spectrum Analyzer ...

Noise is all around us, and while acoustic noise is easy to spot using our ears, electronic noise is far harder to quantify even with the right instruments. A spectrum analyzer is the most convenient ...

Let’s say a corporate engineer or a consultant is coming to your station to diagnose and repair a problem using an RF spectrum analyzer. This would be a great time to schedule a meeting with your ...

The RTL-SDR dongles get most of the love from people interested in software-defined radio, but the Pluto is also a great option, too. [FromConceptToCircuit] shares code to turn one of these radios ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

One of my favorite companies, Mini-Circuits, developed a (really!) low-noise, broad band, preamp (model PSA4-5043+) earlier this year for use as a front-end amplifier for mobile telecom applications, ...
