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.

Методики оценок влияния основных факторов и погрешностей на измерение электромагнитного излучения от печатной платы в ближней зоне

Представлены методики оценок и погрешностей, возникающих при проведении измерений излучения от печатной платы в ближней зоне. Измерения осуществляются с помощью экспериментальной установки, реализованной на основе международного стандарта IEC-61967-3. Особенность установки заключается в использовании системы пробников, позволяющей сканировать все компоненты излучения одновременно. Учет погрешностей и оценок влияния на исходное излучение приводится именно для экспериментальных систем, позволяющих сканировать полный вектор излучения.
