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

ETS-Lindgren's Model 5405 GTEM! Test Cell enables users to perform radiated emissions and radiated immunity tests in less time than either an OATS or in a chamber. Tests can be performed quickly and accurately throughout the product life cycle. Beginning with design qualification testing and moving through to pre-compliance testing, full-compliance testing, and production sampling, the Model 5405 GTEM! Test Cell 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 Model 5405 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 a decade, and is field proven daily at more than 400 installations worldwide.

Measurements made with a GTEM! Test Cell 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 backwall removes 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.
