The 5402 GTEM! Cells from ETS-Lindgren are Test Cells that operate from DC to 20 GHz. They enable users to perform radiated emissions and radiated immunity tests in less time than either an OATS or in a chamber. A typical radiated emissions test (10,000-point scan) can be completed in 15 minutes or less, while a typical radiated immunity test can usually be completed in half the normal time. The test cells have a unique tapered shape, offset septum, resistive termination network, and absorber-lined back wall removing the performance limitations of TEM cells and boxy enclosures.

The 5402 GTEM! Cell Conduct measurements that comply with FCC for Parts 15 & 18 for radiated emissions testing and comply with EC 61000-4-3 Annex D for immunity testing. They are fitted with an external hatch on the upper surface to support emission and immunity measurements on Integrated circuits (ICs) to the SAE J1752/3, IEC 61967-2 and IEC 62132-1 standards. These test cells are available in enclosure that measures 0.50 x 1.40 x 0.75 m with a septum height of 250 mm.
