Abstract
A system, device and method for optimization of a radiated transmission matrix by the selecting probe antennae and applying a compensation network in the test system are described. Among other benefits, the anechoic chamber in which the DUT is disposed is comparatively small and inexpensive. The time-consuming process of inverse matrix tuning or isolation level checking that plagues known systems, device and methods of testing DUT is substantially avoided. Because of small size of shield box and probe antenna selection algorithm, low path loss and acceptable power in testing can be realized.
