GTEM cells are a testing site for effective radiation immunity and emission testing in a single, controlled and protected environment.Compared with other test sites, GTEM test has higher accuracy and better reproducibility. In principle, the GTEM chamber is coaxial extension of the pyramid with 50 unique impedance.At its end, the line terminates the combination of the above impedance matched by the termination resistor and the rf absorber design and construction. The GTEM 1250 has a maximum spacing of 1250 mm and is suitable for radiation and immunity testing. Emissions and immunity tests in a single, shielded environment Meet basic standards: IEC/EN 61000-4-20 IEC and CISPR 14-1,61000-6-3 IEC 61000-6-4 are EUTs connection-free cables Standard: EN 60118-13 immunization tests Ideal design qualification and pre-certification The resulting fields are largely homogeneous, and simple calculations for efficient power conversion require smaller power amplifiers
