© 2019 IEEE. In this study, we perform measurements of electromagnetic emanations from a printed circuit board in the near field on the basis of the IEC-61967-3 international standard. In this standard, engineers use a special measurement system that allows implementing a planar method for scanning electromagnetic emanation. The advantage of this approach is higher measurement accuracy. For these reasons, planar scanning method becomes the most popular. However, in this approach it is necessary to take into account various kinds of effects that affect the original radiation. In this paper, we give estimates of the influence of various factors on the original radiation from a printed circuit board in the near field.
