GTEM Cells




The GTEM cell is a TEM waveguide with the upper-frequency limit extended to the GHz range. It is a low-cost alternative measurement facility for both radiated emission and immunity measurements. It is included in the published standard IEC 61000-4-20 “Emission and Immunity Testing in Transverse Electromagnetic (TEM) Waveguides”.
Compared to EMC testing in anechoic chambers or OATS (Open Area Test Sites), GTEM cells offer some significant advantages for the testing of small and medium-sized EUT´s up to a frequency range up to 18GHz. Quick turnarounds of the EUT as well as numerous testing variations are easy and fast to handle. Switching from emission to immunity testing requires only simple adjustments from receiver input to the amplifier output. Whether you are at the design qualification, pre-compliance, compliance, or production sampling stage, the GTEM can be the right choice for you.

We can configure these GTEM cells with numerous electrical options including internal illumination, filters, and safety interlocks among others, as well as mechanical options including door windows, feed-throughs, and fans. See GTEM Accessories datasheet for a complete list of available accessories.
