Abstract
A spectrum analyzer including a signal receiving and processing unit, a sampling unit, a histogram measuring unit, an arithmetic unit and a display unit. The signal receiving and processing unit receives an input signal according to the desired frequency sweep information. The sampling unit samples a signal output from receiving and processing unit, according to a plurality of threshold values and outputs a plurality of output codes corresponding to sample values of the envelope of the input signal. The histogram measuring unit measures a group of histograms corresponding to the output codes produced by the sampling unit. The arithmetic unit calculates the amplitude probability distribution (APD) of the output signal based on the histograms. The display unit displays a band group having a plurality of the ranges calculated by the arithmetic unit as an area in different states.
