Broadband DCI as a multi usable EMC-test method

The direct current injection (DCI) Method offers in principle an advantage as an EMC test method to test systems against radiated low frequencies. This advantage has lead EADS-military air systems to the plan to use this method also for higher frequencies and to eliminate the restriction to test only to the first half wave resonance. Therefore a research program with the German Federal Office of Military Technology and Procurement (BWB) was raised in 2003 to evaluate the multiple use of DCI for indirect lightning, HIRF (high intensity radiated fields) and EMP (electromagnetic pulse).
