<P>PROBLEM TO BE SOLVED: To provide a spectrum analyzer capable of measuring accurate electric power when measuring a wide-band signal. <P>SOLUTION: A frequency characteristic correction unit 14 includes an equalizer 30 and an equalization coefficient storage section 31 which stores an equalization coefficient of the equalizer 30. A detection unit 15 detects a digital signal having frequency characteristics corrected on condition that a reference signal for correction for correcting frequency characteristics unique to a frequency conversion unit 12 is input to the frequency conversion unit 12, and a control unit 17 stores the equalization coefficient based upon a detection result of the digital signal obtained by the detection unit 15 in the equalization storage section 31 for a center frequency of a frequency band to be measured. <P>COPYRIGHT: (C)2013,JPO&INPIT |
