1. An apparatus for studying the electromagnetic behavior of an electromagnetic wave-emitting or electromagnetic wave-receiving tool, said apparatus comprising:
an anechoic chamber configured to receive the tool as well as a person handling the tool;
at least one analysis antenna configured to pick-up the electromagnetic waves emitted from or received by the tool;
means for processing signals outputted by said at least one analysis antenna to form a video display signal; and
means for displaying a radiation diagram associated with the tool based on the video display signal, said means for displaying the radiation diagram including a display screen and being entirely disposed inside the anechoic chamber to enable the person handling the tool to observe how the handling of the tool affects its electromagnetic behavior.
