Modeling and Practical Suggestions to Improve ESD Immunity Test Repeatability

Electrostatic discharge (ESD) immunity tests are widely carried out in order to assess the immunity level of several electrical and electronic equipment. ESD is a severe source of interference which can produce damages, upset or failures in any electronic system. One important outcome of the ESD tests is the evaluation of the test uncertainty, mainly the uncertainty contribution associated to the repeatability, that is usually very low. The main problems affecting the uncertainty evaluation are underlined. The aim of the paper is to suggest improvements in the measurement set-up, by means of both practical and modelling solutions
