FIELD: physics.SUBSTANCE: device for object electromagnetic test comprises a network of electromagnetic probes (2), structure (3) to support probe network (2) and support (4) for supporting tested object. In compliance with the invention, structure (3) is closed in three space dimensions completely surrounding support (4) of the tested object by means of at least one conducting wall (31) generating Faraday cage, which on its inner side is lined with anechoic electromagnetic radiation absorbers (5) located between probes (2) at certain intervals. In a closed volume, limited by support structure (3), system (6) of relative displacement is located for relative displacement of support (4) relative to support structure (3) at least with one degree of freedom and system (6) of relative displacement (6) arranged inside the support structure (3), is formed by at least with one first system (60) of relative angular displacement ensuring execution of at least one of the specified slide angular displacement (A1) of support structure (3) relative to support (4) around the non-vertical geometrical axis. Support structure (3) rests on lower base (61), at that between base (61) and support structure (3) the second other system (63) of angular displacement is located, which enables to move support structure (3) relative to base (61) on the second angle (A2) with the same absolute value and opposite to sliding movement (A1) of the first system (60) of relative angular displacement of support (4) relative to support structure (3) so that support (4) for the tested object remains in specified and, in fact, constant position relative to vertical.EFFECT: invention relates to studying electromagnetic radiation from different equipment in closed space, for example, in anechoic chamber.15 cl, 13 dwg |
