GTEM Italia GTEM 750 Side view
The GTEM 750 is a TEM waveguide with the upper frequency limit extended to the GHz range. It is under consideration as an alternative measurement facility for both radiated emission and immunity measurements. It is included in the standard IEC 61000-4-20 “Emission and Immunity Testing in Transverse Electromagnetic (TEM) Waveguides”.
There are two models of the GTEM 750 to choose from:
GTEM 750 A
Shipped Assembled. Made with  65cm  pyramidal carbon-foam absorbers (RAM)
GTEM 750 K
Shipped In Kit. Assembly Required! Made with  65cm  pyramidal carbon-foam absorbers (RAM)


GTEM ITALIA GTEM 750 EUT Size and Placement ImageThe GTEM 750, 800 and 800 F use the same metal case.
The difference is the absorbers and ferrites.
