According to the present invention, unnecessary electromagnetic radiation from the hard disk alone is measured by connecting one end of a hard disk drive which has an interface cable and a power cable extending out from the other end thereof to a conductive jig extended along the extension direction of these cables; configuring a coaxial-structured transmission line with the jig, the hard disk drive and the cables which are arranged in this order along the extension direction of the cables and a hollow conductive enclosure covering the jig, the hard disk drive and the cables; and measuring common-mode current flowing through the interface cable and the power cable and potential of the conductive enclosure at the same.
A method of measuring unnecessary electromagnetic radiation using a hollow conductive chassis, in a state where an interface cable and a power cable that are connected to a hard disk are routed outside the conductive chassis and the hard disk is fixed to the conductive chassis through the use of an insulating member, the method comprising:
An apparatus for measuring unnecessary electromagnetic radiation, comprising:
