摘要:
Provided is a measurement apparatus that measures power of a modulated signal that is modulated with a carrier signal having a prescribed frequency, comprising an AD converting section that outputs a digital modulated signal obtained by AD converting the modulated signal; a frequency converting section that converts the digital modulated signal into a frequency component signal representing a plurality of signal components at respective frequencies; a correction coefficient output section that outputs, for each frequency, a correction coefficient corresponding to a frequency characteristic of a transmission path on which the modulated signal is transmitted; a correcting section that corrects the signal component of each frequency in the frequency component signal using the correction coefficient of the corresponding frequency; and a power calculating section that calculates the power of the modulated signal based on the signal component of each frequency in the corrected frequency component signal.
