Near field measurement of the characterization of electromagnetic pollution generated by electronic components arranged on a printed circuit activity fields is important in electromagnetic compatibility measurements. A widely used principle consits in a measuring table on which the electronic board is in operation. A controlled movement of two or three axis sensor is moved in a point to point parallel above the table in a predetermined plane mesh. Each measurement point in the mesh is stored. Then, a mapping field is built and the effective provision of the card under test is indicated on the field map obtained. This measurement requires certain precautions and a post-processing. The swing arm scanner overcomes some of these limitations by providing quick, high resolution direct measurements. The scanner is made ​​from composite materials so as to remain neutral for EMC.
