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 GTEM500 has a maximum spacing of 500 mm and is suitable for radiation and immunity testing. Emissions and immunity tests in a single, shielded environment Basic standard: IEC/ en61000-4-20 IEC and cispr14-1,61000-6-3iec 61000-6-4 are the EUTs connection-free cables Standard: en 60118-13 immunization test Ideal design qualification and pre-certification The resulting fields are largely homogeneous, and simple calculations for efficient power conversion require smaller power amplifiers Excellent standing wave ratios do not require measurement of reflected power over the entire frequency range
