The GTEM 250A-SAE-R from AMETEK CTS GmbH is a GTEM Cell designed for radiated emissions and immunity testing from DC to 20 GHz. It has a maximum septum height of 250 mm and supports EUTs up to 0.20 x 0.20 x 0.15 m. This cell operates with a nominal impedance of 50 ohms and has a return loss of 19 dB with a VSWR of less than 1.25:1. It has a shielding effectiveness of 100 or 90 dB, and can handle input power up to 100 W. 

The GTEM 250A-SAE-R provides a shielded, efficient test environment ideal for pre-compliance testing in line with IEC/EN 61000-4-20, SAE J1752/3, IEC 62132-2, and IEC 61967-2 standards. It includes a right-side access door with a 20 x 13 cm window, an IC testing opening of 93.4 x 93.4 mm, and a fiber-optic feedthrough. This GTEM cell is available as a desktop unit that measures 1.23 x 0.66 x 0.54 m and has an N-type connector for input.
