The limitations of conventional methods used to measure cable's shielding effectiveness are analyzed. The measurement of shielding effectiveness of cable with electromagnetic radiation method is presented based on the reciprocity theorem. According to the theorem and the definition of shielding effectiveness, the method can be used to measure cable's shielding effectiveness through the measurement of radiated field instead of the measurement of coupling field. The electromagnetic radiation method was used to measure the shielding effectiveness of cable with SYV50-5 cable for electromagnetic pulse. The measurement proves to be very efficient in cable’s shielding effectiveness test. As it has no special requirements but linearity on the media space, the reciprocity theorem can be applied re
