ELECTROMAGNETIC INTERFERENCE MEASURING DEVICE AND ELECTROMAGNETIC INTERFERENCE MEASURING METHOD

摘要

Provided is an electromagnetic interference (EMI) measuring device. The EMI measuring device according to the present invention includes an electromagnetic wave eliminating unit eliminating remaining electromagnetic waves from a DUT in response to an eliminating control signal of the control unit. The control unit may calculate EMI of the DUT on the basis of a measured result measured before the elimination of remaining electromagnetic waves. The EMI measuring device according to the present invention may compensate for an error due to remaining electromagnetic waves and measure EMI at high accuracy.
