CONDUCTION DISTURBING WAVE MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To propose a conduction disturbing wave measurement device capable of measuring a disturbing wave, without stopping an operation of a high capacity EUT.SOLUTION: There is provided a conduction disturbing wave measurement device for measuring a conduction disturbing wave from a measurement object appliance, comprises: a first terminal for connecting to the measurement object appliance; a second terminal for connecting to a counter device of the measurement object appliance; an impedance adjustment part provided on a wiring between the first terminal and the second terminal; a switch part which is connected in parallel to the impedance adjustment part to the first terminal; measurement means for measuring the conduction disturbing wave; a third terminal for connecting the switch part and the measurement means; and a resonance suppression part for suppressing self-resonance of the impedance adjustment part.SELECTED DRAWING: Figure 3
