Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

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 ...

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 analysis of electrical signals, otherwise known as signal analysis, is a fundamental challenge for virtually all electronic design engineers and scientists. While it provides valuable insight into ...

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

A set of functions are presented for Octave/MATLAB that allow easy, consistent, and properly scaled DFT/FFT analysis of signals and noise. The techniques and functions presented are easily translated ...

The Rigol DSA815 spectrum analyzer The idea of “seeing” RF has always intrigued me, but short of some futuristic goggles, an RF spectrum analyzer is about as close as one can get. And for those of us ...

Digital circuitry can produce a wide range of harmonic frequencies and spectrum analyzers can show you this RF frequency spectrum (power or voltage), versus frequency. They are the one piece of gear ...
