Performance evaluation of Microtik routers according to electromagnetic compatibility testing standards

Abstract

This study presents a detailed analysis of the performance of the MikroTik router, model RB912UAG-2HPnD, according to European and international electromagnetic compatibility test standards. Tests included measurements of conducted and radiated emissions, harmonic current emissions, flicker and voltage fluctuations, as well as evaluation of equipment immunity to radiated electromagnetic fields, conductive induced radio disturbances, electrostatic discharges and rapid voltage pulse trains in accordance with the product standard SM EN 301 489-1, the emission requirements standard SM EN 55032, and the standard series for immunity tests SM EN IEC 61000. The test results showed that the router complies with all necessary requirements, with significant passing margins above the established limits. For example, the conducted emissions from the power and network ports had minimum pass margins of-14.33 dB to 23.128 MHz and-9.29 dB to 23.128 MHz, respectively. Radiated emissions below 1 GHz and above 1 GHz demonstrated compliance without exceeding the established pass margins. Electrostatic discharge tests and exposure to radio frequency electromagnetic fields confirmed that the router meets the specified performance criteria, ensuring proper operation under electromagnetic interference conditions. Measurements of harmonic current and voltage and flicker fluctuations indicated the router's compliance with applicable standards, demonstrating a power consumption below 75 W and a level of voltage fluctuations that does not affect equipment performance. During and after the immunity tests, the router performed as intended with no loss of functionality or critical stored data. These results emphasize the reliability and stability of the MikroTik router, highlighting the importance of compliance with strict electromagnetic compatibility standards for use in critical environments. The evaluation provides a solid basis for adapting the router to applications that require strict electromagnetic standards, ensuring robust and reliable performance.
