Using the FFT Function of Oscilloscope

This video shows how to use the FFT function of RIGOL oscilloscopes. The FFT function allows the user to measure the frequency and time domain of the signal waveform, at the same time. In this ...

FFT function versus vector-signal-analysis software on a scope

I’m out traveling this week, so my good buddy Darren McCarthy, an RF guru here at Tektronix, is going to fill in for me. My university math teacher always told me (in a thick Russian accent) that when ...

Where Does FFT Process Gain Come From?

Specifications for analog-to-digital converters (ADCs) often include a fast Fourier transform (FFT) plot, such as the one shown in the figure, for a 12-bit ADC with a single-frequency input signal. In ...

How is Fast Fourier Transform Used Alongside Electron Microscopy?

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 ...
