Claim Text:
1. An electromagnetic interference (EMI) measuring device, comprising: a control unit; an electromagnetic wave generating unit configured to generate a first electromagnetic wave in response to a frequency control signal of the control unit; an electromagnetic wave applying unit configured to provide the first electromagnetic wave to a device under test (DUT); a measuring unit configured to repeatedly measure, in response to a measuring control signal of the control unit, a second electromagnetic wave that is emitted from the DUT in response to the first electromagnetic wave; and an electromagnetic wave eliminating unit configured to eliminate remaining electromagnetic waves from the DUT in response to an eliminating control signal of the control unit between measurements of the second electromagnetic wave by the measuring unit, and wherein the control unit calculates EMI of the DUT on the basis of a measured result of the measuring unit.
