The spectrum analyzer includes an input (115) adapted to receive an input signal and a mixer (30), coupled to the input. The mixer is adapted to produce a down converted signal from the input signal. The spectrum analyzer further includes an adjustable decimation circuit (112), coupled to the mixer, that selectively decimates the down converted signal, a decoder (108), coupled to the mixer, that selectively controls the frequency of the down converted signals from the mixer to measure power over a frequency spectrum of the input signal.
L'invention porte sur un analyseur spectral comportant une entrée (115) recevant un signal, et un mélangeur (30) relié à l'entrée et produisant à partir du signal d'entrée un signal un signal de fréquence abaissée. L'analyseur spectral comporte en outre un circuit réglable de décimation (112) relié au mélangeur et décimant sélectivement le signal à fréquence abaissée provenant du mélangeur de manière à mesurer la puissance sur le spectre de fréquence du signal d'entrée.
