Engineeringly Equivalent Method of Replacing High Field Radiation for Two-wire System

To simplify the operation steps of bulk current injection (BCI) instead of high field radiation test and ensure the error is within the controllable range, the analysis and calculation model of the response of the equipment under test (EUT) has been established without a current probe under radiation condition and a current probe under injection condition. The engineeringly equivalent method of bulk current injection replacing high field intensity radiation test is proposed and verified by test. The research results show that the equivalent test error can be controlled within 1dB, which meets the actual requirements of the project.
