Frequency-domain displays show a parameter (usually amplitude) versus frequency. A spectrum analyzer takes an analog input signal (a time domain signal) and converts it to the frequency domain. The resulting spectrum measurement shows the energy of each frequency component at each point along the frequency spectrum.<br> | Frequency-domain displays show a parameter (usually amplitude) versus frequency.
