Abstract
A testing apparatus for electromagnetically sensitive equipment includes a housing defining a testing chamber. The housing blocks transmission of electromagnetic waves from an external environment into the testing chamber and reduces reflection of electromagnetic waves within the testing chamber. The testing apparatus also includes a tube defining an air flow path between the testing chamber and the external environment. The tube blocks transmission of electromagnetic waves from the external environment into the air flow path. The tube includes a proximal end coupled to an opening in the housing such that the air flow path is fluidly coupled to the testing chamber via the opening, a distal end opposing the proximal end, and a bent segment extending between the proximal end and the distal end.
