Noise source monitoring device and noise source monitoring method

摘要

A noise source monitoring device (10) comprises a first storage unit (33), which stores recorded image data (IID), a second storage unit (35), which stores recorded waveform data (OWD), a processing unit (37), which for each of the switching units (17) calculates the degree of correlation between the occurrence of noise and the actuation of the switching unit (17) on the basis of the recorded image data (IID) and the observed waveform data (OWD), and a display control unit (40) which causes a display unit (32) to provide information display that indicate the degree of correlation.
