PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which an electromagnetic environment can be measured so as to remove a measuring strain error generated in a sensor by a method wherein a feature amount which features an output waveform from the sensor is received on the side of an input, a feature amount which features an input waveform is received on the side of an output and a neuronetwork which expresses the relationship between the input and the output is constituted. SOLUTION: In a measuring system, the time waveform of a sensor input signal generated by a pulse generator 4 is input directly to a channel ch1 at an oscilloscope 2 via a conductor 6, a current which flows in the conductor 6 is detected by a current probe 3, and a detection time waveform (a sensor response output waveform) is measured simultaneously with the original waveform (the time waveform of the sensor input signal) by a channel ch2 at the oscilloscope 2. By the measuring system, the discrete value and the feature parameter of an input waveform and a response waveform can be grasped. As the feature parameter, the peak value of a time waveform, a rise rate, a pulse half-width, the integrated value of the waveform of the amplitude value of a preliminarily prescribed time width and the like are enumerated. |
