Abstract :
The emission of electromagnetic (EMI) noise form printed circuit board (PCB) are studied. The different kinds of PCB shape are used for producing electromagnetic field. The field are measured using near-field probe with termination load. The anomaly is detected through the monitoring of the spectra´s amplitude frequency by injecting a voltage pulse at PCB configuration. The measured results are compared to the calculated results using finite element method (FEM) and transmission line model. The relationships with measured electromagnetic field on PCB and calculated results are discussed
