Reverberation Chamber
Reverberation Chamber

A Reverberation Chamber is utilized to induce electric fields into a product using intrinsic isotrophy and uniformity. The chamber at L3 Cincinnati Electronics (L3 CE) is utilized from 100 MHz to 18 GHz to induce pulsed and average electric fields according to the practices established in commercial aviation and military standards. Radiated field testing in a reverberation chamber results in much higher repeatability and the elimination of a product’s inherent directivity. The intrinsic characteristics of a reverberation chamber can also be utilized to measure the emissions of a product as well.

Typically, electronics are mounted inside an electronics bay or inside a vehicle where exposure to radiated fields results in a reverberation effect where electric field polarization information is lost. The reverberation chamber permits the fields to be applied in an isotropically uniform manner inside the chamber.

Overview

  • Intrinsic field isotrophy and uniformity
  • State-of-the-art technology
  • Emissions and susceptibilities

L3 Cincinnati Electronics’ Aluminum Reverberation Chamber is utilized to provide an isotropically, uniform radiated field for simultaneous exposure for system level testing. Given a product’s operation application, a reverberation chamber is better suited for testing as the products do not sustain plane wave electric fields in their operating environments.
