Design of a Reference Device for Burst Immunity Interlaboratory Comparison

In order to improve and to standardize the quality in EMC testing services, increasing efforts have been given in the organisation of interlaboratory comparisons and proficiency testing. Several devices have been designed and realized for this purpose for various emission and immunity tests. In this publication, we pursue this development and propose a new reference device for interlaboratory comparisons and proficiency testing services in electrical fast transients/burst immunity testing according to IEC 61000-4-4. The device is equipped with adapted detecting circuitry to measure and record the burst pulses and relevant parameters for offline evaluation. The concept and the architecture of the device and its operation principles are explained in detail. The preliminary evaluation of its stability and linearity is performed and its capabilities to detect errors in a typical testing scenario is explained.
