Abstract. An experimental setup based on the international standard IEC-61967-3 has been implemented. This setup implements a planar method of scanning from a radiating structure. A printed circuit board is investigated as a radiating structure. The main feature of the installation is a system of  3 mutually perpendicular probes. This system allows us to scan radiation from all components simultaneously. However, when conducting measurements, it is necessary to take into account various kinds of factors affecting the initial radiation. This paper provides methods for assessing the influence of various factors affecting the initial radiation from a printed circuit board. The obtained radiation results after preliminary processing are used in the problem of localization of radiation sources. This task is especially relevant in EMC.

Key words: experimental setup, printed circuit board, near field.
