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 ...

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 ...

The Rigol DS1000 series of oscilloscopes are popular with hobbyists for good reason: they provide decent specs at a low price. However, their spectrum analysis abilities are lacking. While these ...
