The GTEM cell concept; applications of this new EMC test environment to radiated emission and susceptibility measurements

The use of a TEM-cell anechoic chamber hybrid, the GTEM cell for EMI testing, is discussed. The hybrid chamber may be used for both susceptibility and radiated emission testing and is well suited for time domain as well as continuous wave (CW) measurements. The chamber has extremely broadband characteristics, with a usable frequency range from DC to GHz (~18 GHz). The TEM mode is used to simulate an incident plane wave for susceptibility testing. Radiated emission data obtained in the hybrid chamber may be used to simulate open area test sites (OATS) or free space measurements. Applications will be stressed and a variety of representative data will be shown
