If you want to know more about Teseq GTEM Cells / TEM Cells

The GTEM cell is a frequency extended variant of the traditional TEM (Transverse Electro-Magnetic) cell. The GTEM cell is, in principle, a tapered coaxial line (offset septum plate), which is terminated by a combination of discrete resistors and RF absorbers to achieve a broadband match. Designed for EMC applications, calibration of antennas/field probes, test and measuring of mobile phones and screening measuring of material.

AMETEK CTS via its Teseq product range was one of the original licence holders for the manufacture and supply of GTEM cells. Consequently, the Ametek CTS RF EMC team have over 20 years of experience in the design, installation and calibration of GTEM based RF Immunity test systems. The new AMETEK CTS standard GTEM test packages provide a simple, guaranteed pre-defined solution for your testing needs. Our expert team of RF EMC Engineers are ready to help you to add any customisation required to the GTEM such as additional power or signal filters, air or water access, DUT manipulators etc. AMETEK CTS offers pre-defined systems sizes from GTEM 250 till GTEM 2000 with the possibility of customized options.
