Know the Limitations of Your Scope’s FFT Capabilities

An oscilloscope’s FFT function can tell you the frequency content of an acquired signal. Most digital scopes–even those costing less than $400–have the ability to perform a Fast Fourier Transform (FFT ...

Measure frequency response on an oscilloscope

Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

FFT Function

where x is a 1 ×n or n ×1 numeric vector. The FFT function returns the cosine and sine coefficients for the expansion of a vector into a sum of cosine and sine functions.
