Abstract(in Japanese) (See Japanese page)
Abstract(in English) An APD (Amplitude Probability Distribution) measuring equipment has been developed that can perform high-speed measurement of amplitude distribution by combining multiple M-sequence counters having relatively prime cycles and by using residue number systems. Moreover, by using a wideband APD measuring equipment that combines this developed equipment with a high-speed logarithmic amplifier having a reception bandwidth of 500MHz, T_r=10nsec, T_f=30nsec, APD of disturbance leaked from a microwave oven and of disturbance from electrostatic discharge were measured in a semicontinuous manner over a long time period at a bandwidth of 100MHz. At the same time, the video output from a spectrum analyzer used for standard disturbance measurements was connected to the APD measuring equipment and APD measurements with video output were performed under a resolution bandwidth of 1MHz. Finally, with regard to disturbance from a microwave oven, two sets of a spectrum analyzer and APD measuring equipment combination were used as proposed by CISPR to perform weighting measurements (10Hz video bandwidth) simultaneously with APD measurements having a 3MHz video bandwidth. the measurement data so obtained are examined and compared and results are presented.
