EMC testing for different types of interference sources

Multipoint interferences approaches for EMC prediction of communication systems in the complex electromagnetic environment, previously have been proposed by the authors. Now a new analytical method of multipoint interference for EMC testing is present. This method is developed to consider different types of interference sources. It has been shown at previous papers the relationship between the threshold EMC testing both at the sources output (checkpoint) and system inputs. Usually, those thresholds for interference exceeding are choose similar to signal levels desired. In this paper four types of the interference models are considered as interference source output and input signal at any block of the communication systems, where the relationship between the thresholds for EMC testing give opportunity to select any appropriate threshold to measure the interference at any point of interference propagation paths from the source output selected as check point for interference control
