Abstract
A digital modulation signal measuring device of the present invention is designed to generate a signal string of an ideal base band component after correcting frequency deviation of a base band component included in a digital modulation signal to be measured, detect a noise component included in the digital modulation signal based on this ideal base band component, and output (display) the spectrum of the detected noise component together with the spectrum of the base band component. Therefore, according to the digital modulation signal measuring device of the present invention, it is possible to easily recognize the quality of a noise component included in a digital modulation signal during actual transmission of the digital modulation signal, to guess the cause of generating the noise and to improve the transfer quality at easy.
