A fully fledged spectrum analyzer on a basic Arduino board? It is possible when the software is tailored to the available processing power. A standard Arduino can be turned into an AC line (‘mains’) ...

The estimated accuracy of phase and frequency of all phase FFT spectrum analysis and its correction techniques are high[1-3], for its perfect characteristic of inhibiting the spectrum leakage. The ...

However, their spectrum analysis abilities are lacking. While these scopes do have a Fast Fourier Transform (FFT) function, it’s limited and nearly useless for RF.

As it was mentioned our goal is boost the learning process, using IT infrastructure along with electronic prototypes, besides encourage students to use their pace in laboratory activities. The work ...

RF signal observation has evolved from yesteryear’s spectrum analyzer to today’s RF recorder. Swept spectrum analyzers, FFT analyzers, and real-time signal analyzers all had limitations. Today ...

The spectrum analyzer uses a fixed number of 1024 samples for each FFT acquisition. That fixed size, combined with an FFT-overlapping process and a FFT rate of 146,484 FFT/s, results in a gap-free ...

I can't believe I haven't figured this out until now, but some of the digital oscilloscopes have FFT functionality built in, which effectively makes them a (poor man's?) spectrum analyzer.Anyone ...
