Measurement of Electromagnetic Interference in the Primary Electromagnetic Laboratory

This paper describe the measurements of the electromagnetic fields present in the precision electromagnetic laboratory in the Faculty of electrical engineering and computing. Because of the many instruments present in the laboratory and the vulnerability to the ambient electromagnetic fields, it was interesting to investigate if the level of exposure to microwave frequencies in the laboratory exceeds the international and Croatian standards. The measurements have been performed in the frequency range from 75 MHz to 3 GHz. The highest fields came from the nearby base station, but still less than 0, 3 V/m, which is app. 0, 5% of the reference level.
