Semi Anechoic Chambers & OATS are now being evaluated from 9KHz-30MHz in order to use them for magnetic field emission testing as per CISPR 16-1-4:2023. For these evaluations, magnetic field Antenna (Loop) in all three orthogonal arrangements ( HX, HY & HZ ) are used. Similar to classical NSA validation, the volumetric test method is applied. The validation is carried out at test distances of 3 m, 5 m or 10 m in a fixed height of 1.3 m above ground plane.
BNN can undertake Certification of the existing chambers (3m, 5m & 10m ) as per the following test standard:-
