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 5402 GTEM! Test Cell enables users to perform radiated emissions and radiated immunity tests in less time than either an OATS or in a chamber. Beginning with design qualification testing and moving through to pre-compliance testing, full compliance testing, and production sampling, the 5402 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 GTEM! 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.

Product Features

GTEM 5402-SAE and GTEM 5402-SAE-D
The GTEM 5402-SAE and GTEM 5402-SAE-D are special versions of the GTEM 5405. These 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, in addition to the traditional immunity and emission measurements to the IEC 61000-4-20 standard, with the DUT mounted in the test volume through the side entry door. The 5402-SAE has a 100mm x 100mm hatch with support clamps to accommodate a 100mm x 100mm PCB. The 5402-SAE-D has a larger 150mm x 150mm hatch and can accommodate both 150mm x 150mm PCBs and the smaller 100mm x 100mm boards.

VSWR Levels

The average VSWR is 2: 1 above 50 MHz, an excellent level at this low frequency for an antenna this size.
