The Mode Stirred chamber is essentially a large microwave oven. It consists of a metal room that serves as a high-Q chamber and a metal paddle wheel to "stir" the chamber modes. Mixing the modes in this manner allows test objects, in a single orientation to be exposed to EM energy in many different angles of incidence and polarization.
Electronic susceptibility tests can be performed, or test object electromagnetic transfer functions can be determined through measurements of shielding effectiveness, and cable effective height. Electric fields inside the chamber are monitored by 4 monopole antennae. Testing can be performed on six customer data channels at one time, up to 40 GHz, with the spectrum analyzers.
