Intermodulation measuring method and device

摘要: PROBLEM TO BE SOLVED: To provide an intermodulation measuring method and device whose measurement lower bound of the intensity ratio a tertiary modulation distortion component to given fundamental is low. SOLUTION: The for evaluating nonlinearity object 15 composed step inputting plurality signals different in frequency 15, selectively attenuating 14b range not less than measured value, out components having same values as inputted distorted wave from which are contained output signal observing 16 spectra by observed after attenuation.
