Electronics Laboratory – Electromagnetic Field Emitted by Oscilloscopes

Abstract

In the article the need for research the electromagnetic field emitted by electronic laboratory instruments is shown and justified. Theoretical considerations about the essence of the electromagnetic field were surrounded by three oscilloscopes. The tests have shown that laboratory instruments emit electromagnetic waves over a large frequency range from 50 Hz to 200 kHz. The intensity of the electromagnetic field around the tested devices is within the normal range, and is maximum value 5088 V/m (electric component) and 1759 nT (magnetic component).
