The 5405 GTEM! from ETS-Lindgren is a Test Cell that operates from 9 kHz to 5 GHz (RE), and from DC - 20 GHz (RI). It enables 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. Its unique tapered shape, offset septum, resistive termination network, and absorber-lined back wall removes performance limitations of TEM cells and boxy enclosures. Measurements made with this test cell is accepted for final compliance demonstration by the FCC for Part 15 & 18 radiated emissions testing and comply with IEC 61000-4-3 Annex D for immunity testing.
