摘要：
Measurements of electromagnetic compatibility properties of electronic systems are inevitable to guarantee the reliability and safety of control or robotic systems. For automation of such measurements time effective TDEMI (Time Domain ElectroMagnetic Interference) devices are used. Their principally new structure with parallel analog input channels followed by fast digital signal processing provides fast EMI spectrum measurements. On the other side it brings the risk of introduction of new unknown error sources caused by differences between transfer characteristics of parallel input channels. A special pulse model of the errors was proposed. Results of the precise simulation pulse model and simplified theoretical pulse model are compared together and with the experimental test on the harmonic input signal. (C) 2014 The Authors.
