Abstract :
This report describes the characteristics of an anechoic chamber when imitated equipment under test (EUT) is used. Radiated emission measurements revealed that the use of optically driven EUT enhanced the repeatability of the measurement set compared to coaxial cable driven ones. Measured emission levels in the fully anechoic chamber are used to estimate those for the semi anechoic case. Estimated levels agreed within 5 dB with the measured ones
