Abstract: A shielding device having an aluminum outer housing with an open top, an aluminum EMI filter box disposed within the outer housing containing thermocouple, AC signal, DC signal, and power EMI filters allow measurement signal input to an aircraft engine tester disposed within the shielding device. A display window formed of a conductive bezel, EMI gaskets, a woven bronze screen, and an aluminum backup panel, various switches, and a top access panel are mounted on a conductive deck covering the open top of the outer housing. Connections between conductive elements use closely spaced screws, high conductivity finishes, and EMI gaskets to ensure that high intensity EMI can be shielded from the aircraft engine tester enclosed within.
