Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...

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’s RF ...

A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis ...

Swept-Tuned Spectrum Analyzers are instruments used to measure and display the frequency spectrum of an input signal. They provide a visual representation of the magnitude of the Fourier transform of ...

In earlier articles, we looked at the basics of fast-Fourier transforms (FFTs) and how to set up an FFT on a modern digital oscilloscope. In this post, we’ll take a brief look at what that modern ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

Having a scope in a home lab used to be a real luxury, but these days, its fairly common for the home gamer to have a sophisticated storage scope (or two) hanging around. Dedicated spectrum analyzers ...

APU Spectrum Analyzer is a free spectrum analysis tool supporting a variety of FFT configuration options. You can adjust the FFT window type (Rect, Hann, Hamming, Blackman, Kaiser) and size (from 64 ...
