Recognizing that electromagnetic compatibility (EMC) test chambers require a lot of laboratory space, design engineers at ETS-Lindgren sought to reduce the footprint of such equipment. The smaller-scale solution reflected in the recently developed SpaceSaver 26H EMC chamber offers a new approach in radio frequency (RF) shielding design.

The modular RF shielded semi-anechoic chamber addresses test lab space constraints with nominal inside shield dimensions of 7.45 m × 3 m × 3 m. While smaller than a typical chamber, the design maintains the requisite 3 m dimension critical for radiated and conducted emissions measurements. Rigorous testing,Source: ETS-Lindgren including shield verification and anechoic testing, confirm the chamber's exceptional shielding properties and its ability to deliver controlled and accurate testing environments.

The RF shielded door, equipped with a limit switch, measures 1.1 m x 2 m and features a two-piece aluminum custom door ramp with a weight capacity of 317 kg to enhance accessibility. DuraSorb absorbers installed on the chamber walls produce high-performance test results across various frequency bands by absorbing reflections. The chamber’s reflectivity exceeds 35 dB at frequencies above 8 GHz. The absorber’s power handling capacity is 106 W/m².

The chamber incorporates ETS-Lindgren’s 7-TR/POL tripod antenna positional, which uses non-metallic, non-reflective materials that will not distort measured data. The floor is configured with a raised 6.5 inch ground plane equipped with access hatches and a dielectric floor underlay with vapor barrier that supports a turntable.
