  • Patent number: 10228397
    Abstract: A measuring apparatus is provided for electrical signals. The measuring apparatus includes an analog-to-digital (A/D) converter configured to A/D-convert an analog signal to be measured, and an integrator configured to perform integration time processing for a plurality of digital values output from the A/D converter based on an integration time. The integrator is configured to output a plurality of measured values obtained by the integration time processing. A noise level calculation unit is configured to calculate a noise level of the analog signal to be measured from the plurality of measured values obtained by the integration time processing, and a display unit is configured to display noise levels corresponding to a plurality of integration times.
