The GTEM-250 from GTemCell Group is a TEM Waveguide Cell that operates from 9 kHz to 3 GHz (emissions) and 80 MHz to 6 GHz (immunity). It is designed to offer a compact solution for conducting EMC emissions and immunity testing of small/medium-sized Equipments Under Test (EUTs) as per the IEC/EN 610000-4-20 standard. This test cell enables quick turnarounds of EUTs, easy handling of several testing variations, and simplified switching from emission to immunity tests. It has a test area of 8.3 x 8.3 x 8.3 cm and supports an EUT size of up to 20 x 20 x 15 cm. This cell can handle an input power of up to 1 kW (continuous) and 2.5 kW (pulsed) and has a VSWR of less than 1.6:1. 

The GTEM-250 is made of ruggedized hot galvanized steel with an INOX steel door and has carbon loaded polyurethane pyramidal foam that has a height of 15 cm. This TEM cell measures 125 x 64 x 44 cm and has 7/16 & N-type connectors.
