High intensity electromagnetic field radiation effect equivalent test method for spectrum-dependent equipment

Aiming at the error caused by the limitation of the existing differential-mode injection equivalent test method,the reason for the error is analyzed based on the electromagnetic field theory.The correction method with the antenna as the coupling route is proposed.The equivalence between the injection test result and the radiation test result required by the test standard is realized.The spectrum-dependent equipment which is prone to interference damage effects in a complex electromagnetic environment is used as the research object.The communication radio is used as the equipment under test(EUT).The in-band and out-of-band blocking effects strong field electromagnetic radiation equivalent injection test is carried out.A correction method for the simultaneous existence of working signals and interference signals is proposed and verified by experiment.The results show that the equivalent electromagnetic radiation method of the differential mode injection method has a high accuracy,with the receiving antenna as the main coupling route.The electromagnetic power required by the equivalent injection test is significantly less than that of the radiation test.
