Susceptibility of Electronic Devices to Variable Transient Spectra

The subject of this paper is to investigate the susceptibility of microcontrollers to single transient signals. It is shown that the principle coupling of transient field pulses into electronic systems is limited in bandwidth. In order to investigate the different resulting pulseforms and to estimate the effect on the susceptibility of the electronic devices a setup is presented that gives the opportunity to emulate the field coupling in systems with different coupling sizes. On the degeneration of the disturbing signals by the input impedance of the chip is given attention as well as on the susceptibility of the chip itself.
