Key Features
  • For all Phases of EMC Testing:
    • Design Qualification
    • Pre-Compliance
    • Full Compliance IEC 61000-4-3 ANSI C63.4
    • Post Production

ETS-Lindgren's Model 5411 GTEM! Test Cell enables users to perform radiated emissions and radiated immunity tests in less time than either an OATS or a chamber. Beginning with design qualification testing and moving through to pre-compliance testing, full compliance testing, and production sampling, the 5411 GTEM! is a time saving device for your test lab. 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 GTEM! Test Cell is based on experience, not experimentation. Originally developed in the EMC Baden (Switzerland) labs of ABB, the cell has been accepted in the EMC community for more than 10 years and is field proven daily at more than 400 installations worldwide. Measurements made with a GTEM! are 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. The GTEM!'s unique tapered shape, offset septum, resistive termination network, and absorber- lined back wall remove performance limitations of TEM cells and boxy enclosures. Electromagnetic wave and RF current termination are smooth and controlled. Field uniformity is +/- 3 dB up to 1 GHz, and +/-4 dB above 1 GHz.
