1. Conducted mode testing

1.1 Driving immunity

The aim of this type of test is to verify the equipment's behavior in the face of radiated disturbances coupled to the wiring, generating mainly common-mode currents (power in the general sense, since currents and electromotive forces are coupled – emf). The frequency range of these powers, in the civil sector, is between a few tens of kilohertz and a few tens of megahertz. In the military and aeronautical fields, the frequency band of aggression extends up to 400 MHz. Thus, despite the fact that this is a conducted test, given the high frequencies encountered, radiated phenomena may play a part in the dispersion of test results (see article
