A novel method for the analysis of ESD generators and coupling using frequency domain

A concept for analyzing ESD generators and coupling to EUTs in the frequency domain is presented. Its novelty lies in not only taking the current shaping, but also the radiation effects of structural elements and electrical components located within the ESD generator into account, without discharging the ESD generator. This is achieved by using the frequency domain and substituting the electrical breakdown within the ESD generator (contact mode) for one port of a network analyzer. The network analyzer excites all the pulse forming and the radiating elements of the ESD generator as they would be excited during a discharge. This offers the advantage of an increased dynamic range of frequency domain techniques without having to simplify the complex radiation properties of real ESD simulators.
