PROBLEM TO BE SOLVED: To provide a frequency characteristic measuring device capable of easily comparing a plurality of the obtained measurement results. SOLUTION: A spectrum analyzer 100 contains at least a set of a local oscillator 22, a mixer 20, and an intermediate frequency filter 24, and includes a signal component extracting means for sweeping frequency of signal components extracting from input signals with a prescribed bandpass by changing an oscillation frequency of a local oscillator 22 within a prescribed frequency range; a measurement means containing a wave detection section 50 etc. to measure a characteristic value with respect to the extracted signal component; a display section 70 with a display screen capable of setting a plurality of display areas; and a display treatment section 60 to display each of a plurality of measurement results respectively on the plurality of display areas correspondingly and separately when the plurality of measurement results are obtained by the measurement means.
