Reverberation chamber verification procedures, or, how to check if your chamber ain´t broke and suggestions on now to fix it if it is

We present three tests for evaluating the agreement between measurements taken in a reverberation chamber and the expected results given by simple statistical models. We then apply these tests to a chamber that is known to be sub-optimal. We also give recommendations on when the data indicate that a chamber might need to be modified, as well as methods for determining whether deviations from optimal performance might be due to the characteristics of the instrumentation connected to the chamber, and not the chamber itself
