RF/EMI Shielded Reverberation Chamber

Category:

Select Fabricators Reverberation Chambers utilize innovative motor induced vibrations of tent walls to achieve an electromagnetic environment suitable for testing immunity, emissions, and shielding effectiveness.

This method allows for smaller enclosure sizes, reduced cost, and higher field-to-input power ratios. Our reverberation chambers operate have a reflective conductive fabric which contain and reflect radiated RF energy. In combination with a fabric rotating paddle stirrer, these enclosures create statistical isotropy and homogeneity across a substantial working volume. Reverberation chambers stand out for their ability to generate robust field strengths with lower power consumption compared to alternative testing environments. This allows for maximized performance while reducing the need for expensive amplifiers.
