The GTEMCELL GTEM 400 family consist of the: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 radio frequency field-immunity test.
GTEM-400 made with 65cm pyramidal carbon-foam absorbers (RAM).
GTEM-450 made with 51cm. EMC Truncated pyramidal absorbers (RAM)
GTEM-450V is the vertical model (suffix V) made with 51cm. EMC Truncated pyramidal absorbers (RAM)
