发明名称 Spectrum analyzer system and spectrum analyze method
摘要 Provided is a spectrum analysis system that measures a signal component at each frequency of an input signal, comprising a sampling section that samples the input signal at prescribed bandwidths to digitize the input signal, and outputs a resulting digital output signal; a converting section that converts the digital output signal from the sampling section into the signal component at each frequency of a unit bandwidth; and an output section that (i) outputs the digital output signal output by the sampling section when a frequency span, which is a frequency range in which the measurement result of the signal component at each frequency of the input signal is output, is greater than or equal to a predetermined reference bandwidth and (ii) outputs the signal component at each frequency converted by the converting section when the frequency span is less than the predetermined reference bandwidth.
