E3 Compliance – Grand Rapids, Michigan

ETS‑Lindgren installed a cutting-edge SpaceSaver™ 26H EMC Chamber, representing a remarkable RF-shielded semi-anechoic chamber technology achievement. This versatile chamber offers a comprehensive solution for a wide range of testing requirements, particularly pre-compliant emission testing. Its compact design, tailored to the specific needs identified by E3 Compliance, provides an exceptional anechoic test environment capable of supporting testing up to 40 GHz.

The SpaceSaver™ 26H chamber boasts an impressive performance that surpasses the stringent standards typically associated with pre-compliant radiated emissions testing and design and debugging applications. This achievement is made possible through the incorporation of ETS‑Lindgren’s finest materials, including advanced anechoic absorbers, and state-of-the-art positioners such as the highly acclaimed EMCenter™ Modular FR Platform, equipped with a 7-slot configuration.

The chamber design has undergone rigorous testing procedures to ensure superior performance and reliability, including Shield verification and meticulous anechoic testing. These measures validate the chamber’s exceptional shielding properties and ensure its ability to provide an accurate and controlled testing environment. This successful installation of the SpaceSaver™ 26H EMC Chamber by ETS‑Lindgren stands as a testament to our commitment to delivering cutting-edge solutions that push the boundaries of technological innovation. It showcases ETS‑Lindgren’s expertise in RF-shielded chamber design and underscores our dedication to meeting the demanding requirements of our clients.

Anechoic Absorbers and Treatments

ETS‑Lindgren installed DuraSorb™, providing a smooth transition from free space impedance to the lossy ferrite tile base. As a result of its optimized design, high performance is guaranteed, both at lower frequency bands and frequencies above 1 GHz.

• It has a reflectivity better than 17 dB from 60 MHz to 3 GHz, and better than 20 dB at above 4 GHz.
• At frequencies above 8 GHz, the reflectivity exceeds 35 dB. Absorber power handling is 0.068 W per in² (106 W per m²) – 200 V/m.
• Model DSH-400H , Partial (16 pcs) coverage with 400 mm DuraSorb™ polystyrene absorber and whitecaps Note: Non-critical areas are covered with polystyrene absorber bases
• Model FT-1500, Full coverage with ferrite panels
• Model DSH-600, Full coverage with 600 mm DuraSorb™ Hybrid Absorber and whitecaps
  Note: Non-critical areas are covered with polystyrene absorber bases
• Model FT-1500, Full coverage with ferrite panels
• Model DSH-600, Full coverage with 600 mm DuraSorb™ Hybrid Absorber and whitecaps

Floors

• Raised 6.5” (16.5 cm) ground plane with three (3) 12” x 12” (30.5 cm x 30.5 cm) access hatches
• Dielectric floor underlay with vapor barrier Note: Height measured above the ground plane raised floor Positioning
• Medium duty turntable – 1.5 m (4’-11”) diameter with a 1,000 kg (2,205lb) weight capacity

Antenna

Users can be confident of accurate measurement results when using the 7-TR/POL Tripod, which is constructed of non-metallic, non-reflective materials that will not distort measure data. The 7-TR/POL Tripod provides increased stability for physically large, ultrabroadband antennas, such as ETS‑Lindgren BiConiLog™.

• Nominal Height: 218 cm (85.83″)
• Nominal Load Capacity: 13.5 kg (29.76lb)
• Max Height: 218 cm (85.83″)
