Metrological traceability of the results of testing for electromagnetic compatibility in accordance with the NATO standards

Ensuring the electromagnetic compatibility of special-purpose equipment used in a complex saturated radio frequency environment requires testing accordance with procedures that guarantee valid verification its immunity to external fields. The paper presents national measurement standards and at National Scientific Centre “Institute Metrology” for NRE02, NRE03 NRS02 AESTR-500 standard. It is shown how metrological traceability SI units results ensured during tests. evaluating uncertainty measurements field strength using NARDA-550 meter ranges 10 kHz – 1 GHz when GTEM chamber, 1-43 anechoic chamber. studies have proven uncertainties, calibrating antenna uneven distribution chamber are most critical. obtained evaluation calibration coefficient high-precision signals both emission being exposed fields disturbances limit values as regards provisions these standards. These discrepancy no more than 0.05 dB confirm characteristics device provided by manufacturer. set test NSC allows special according NATO required accuracy.
