What is spectrum?

A spectrum means the representation of the intensity distribution of an electromagnetic radiation depending on its frequency.

The spectrum generated via a Fourier transform of the signal using a FFT Analyzer is called "frequency spectrum". The frequency spectrum is obtained by dividing the time signal into fixed frequency bands, and represents frequency with the vertical axis and signal strength with the horizontal axis.
