Abstract. The description of the implemented experimental setup for measuring electromagnetic radiation from a radiating structure in the near field is presented. The advantages of measurements in the near field are that the requirements for the measuring installation are reduced, the accuracy of the measurements taken is increased, and the need for an anechoic chamber is eliminated. A printed circuit board is used as an example of a radiating structure. The proposed experimental setup implements a planar scanning method. The advantages of a planar scanning method are the simplicity of calibration and motion control. The proposed measurement setup allows us to measure the full radiation vector at each observation point in one scan pass. Information about radiation can be used to solve inverse problems with the goal of localizing the most active radiation sources located on a printed circuit board. The results of measurements of radiation from a printed circuit board using a measuring setup are presented. Other types of setups for measuring electromagnetic radiation are described: commercial and laboratory solutions. A comparison is made of known types of setups with the proposed radiation measurement system.

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