Comparing EM Susceptibility Measurement Results Between Reverberation and Anechoic Chambers

This paper compares measurement r e s u l t s o b ta in ed using a 2 .7 m x 3.1 m x 4.6 m r e v e r b e r a t i o n chamber and a 4 .9 m x 6.7 m x 8 .5 m anechoic chamber t o determine t h e EM s u s c e p t i b i l i t y of equipment under t e s t (EUT). The frequency range was 200 MHz 18 GHz. The " c o r r e l a t i o n f a c t o r " between th e two te chn iq ues appea rs t o be d i r e c t l y p ro p o r t i o n a l t o t h e gain o f t h e EUT.
