The GTEM cell is, in principle, a tapered coaxial line (offset septum plate), which is terminated by a hybrid combination of discrete resistors and RF absorber to achieve a 50 Ohm broadband match. It is applied for the measure of Radiated emissions and radiofrequency field-immunity tests.

The GTEMCELL GTEM 400 family consists of  the:

GTEM-400 is made with 65cm pyramidal carbon-foam absorbers (RAM).

GTEM-450 is made with 51cm. EMC Truncated pyramidal absorbers (RAM)

GTEM-450V is the vertical model (suffix V) made with 51cm. EMC Truncated pyramidal absorbers (RAM)
