Additional information

The GTEM EMC 500 operates with an electromagnetic field distribution in TEM mode. In this operating mode, the electric and magnetic field components are perpendicular to the propagation direction of the electromagnetic wave.

The GTEM cell is designed for fully configurable feed thrus and filters. Available options include fiber optic leads, filtered RS-232 pass-thrus, RF feed-thrus, shielded RJ45 feed-thrus, power line filters, electrical safety interlock, technical panel, power socket for EUT and shielded IP camera system.

For the GTEM EMC 500, the VPOS option is available. It enables vertical positioning with plastic table over absorbers and 90° turned door position.
