DEVICE OF 3D SCANNING OF ELECTROMAGNETIC EMISSIONS IN NEAR-FIELD OF ELECTRONIC MEANS Russian patent published in 2014 - IPC G01R33/00 

FIELD: instrumentation.

SUBSTANCE: invention relates to measurement equipment, represents a device of 3D scanning of electromagnetic emissions in near-field of electronic means and may be used for measurement of intensity of electromagnetic field during tests, diagnostics and testing of electronic devices and instruments for performance of requirements of electromagnetic compatibility in part of noise emission. The device comprises a measurement module fixed above an instrument table on a bracket with the possibility of movement along height. The measurement module comprises an array of field sensors, each of which is implemented on two mutually perpendicular inductances of surface assembly, outlets of which are connected to inlets of multiplexers of lines and columns; with the help of multiplexers the required field sensor is selected. Thus, measurement of the field in the horizontal plane is carried out without usage of mechanical displacing systems, and with the help of the vertical displacement system they perform measurements at different height from the tested device.

EFFECT: simplified design and accelerated process of measurement during 3D scanning of an electromagnetic field emitted by components and conductors of a printed circuit board of an electronic device.
