The EMC laboratory includes an anechoic chamber for measuring electromagnetic interference (EMI) of electrical and electronic devices in the frequency range from 30 Hz to 18 GHz and an anechoic transverse waveguide (GTEM) for performing radiation and immunity tests according to the IEC 61000-20 standard on technical devices. The advantage of the GTEM is that tests can be performed up to the GHz range with the possibility of extension up to 20 GHz. The GTEM also serves the field of investigating the impact of electromagnetic fields on biological systems, which will also expand the possibility of cooperation with academic institutions and industry that are oriented towards the field of medicine, or similar institutions.

EMI measurements can be performed using an artificial network (LISN) and a special measurement system with preset filters according to EN and IEC standards. The measuring system can also be connected to specially adapted EMC antennas for measuring EMI radiation and, using the supplied probe accessories, also for detecting nearby electric or magnetic fields, which makes it possible to easily and quickly locate the fault location or the source of interfering signals. The advantages of a special measuring system can be used in almost all areas of electrical engineering and other scientific disciplines.

In the EMC laboratory, it is possible to perform harmonic analysis of the current in the power supply of electrical appliances and voltage fluctuations, the resistance of electrical equipment to atmospheric overvoltages, to transient interference in the power supply network, drops and short-term power interruptions.
