The GTEM cell is a frequency extended variant of the traditional TEM cell. Designed for EMC applications, calibration of antennas/field probes, testing and measuring of mobile phones, and other electronic devices etc. The GTEM 250 has a maximum septum height of 250 mm and is suitable for emissions and immunity testing.

A GTEM cell is a design variation of the TEM Cell that allows the cell to operate in the Gigahertz frequency range. The external enclosure forms a long rectangular base pyramid. The GTEM is terminated on a lined surface made of radiation-absorbent material such as carbon-loaded foam, and absorbers line the side walls. A slightly spherical wave ...

GTEM, DTEM, Striplines and Reverberation Chambers (RCs) are modern EMC test environments in addition to the established methods like semi- or full anechoic rooms and open area test sites. They can be used for emission and immunity testing as required by the IEC / EN 61000-4-20, 21 and other standards.

GTEM stands for Gigahertz Transverse Electro Magnetic. This special type of cell has the advantage of having no cut-off frequency as do other types of TEM waveguides. In principle, the GTEM cell is a coaxial line expanding pyramidally and having an impedance of 50 Ω.

2020年2月21日 · Perhaps only seconded by a current probe, the TEM cell (or GTEM) offers a low cost method of measuring emissions from a product as well as being useful for subjecting your product to radiated fields. In some circumstances, GTEM results are even accepted by the FCC for equipment authorization.

A GTEM Cell is an essential tool for RF and EMC testing, offering a compact, cost effective and efficient alternative to traditional anechoic chambers. Its broad frequency support, controlled test environment and high measurement repeatability make it invaluable for pre-compliance testing, product development and regulatory compliance verification.

GTEM (Gigaherz Tanseverse Electromagnetic) Cell Test Chamber is a new type of electromagnetic compatibility test equipment developed based on the TEM Cell Chamber (it applies asymmetric rectangular structure to simulate free space to generate TEM electromagnetic waves inside the small chamber).

Model GTEMCELL GTEM250 F with Ferrite tiles on the bottom offers a wider operating bandwidth with peak smoothed and flat response starting from DC to microwave frequencies. It is an indispensable tool for researchers and developers engineers!

What is GTEM Cell? A GTEM (Gigahertz Transverse Electro Magnetic) cell is a test site for performing both radiated immunity and emissions testing in a single, shielded environment. When you compare with other test sites, you will see that GTEM testing is …

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 Measuring of Radiated Emission, radiofrequency field-immunity test.
