The 3m constricted field anechoic chamber is the optimal solution for the immunization test in accordance with the standard IEC/ en61000-4-3 measuring distance of 3m. Pre-acceptance of emission measurements at this size provides the best performance.The installed ferrite and part of the mixed absorbent allow the measurement of frequencies ranging from 30 MHZ to at least 18 GHZ.The CHC can be either a semi-anechoic chamber (with ground level) or a full anechoic chamber (with floor absorbent on the entire floor surface).In each case, the transmitting antenna and EUT are therefore included in the standard supply.
