EMC Testing and Analysis for Digital Circuit Board

magnetic field antenna and electric field antenna caused by digital circuit board are the most possible electromagnetic interference for the production,and digital circuit board is not necessary for EMC TEST,which can give production engineer much trouble.It′s useful for reducing production cost and production time if EMC about digital circuit board is cared in early days of production research.This paper gives the function of digital circuit board′s EMC test for EMSCAN,and gives the possible reason causing electromagnetic radiation.
