Abstract: A target stand is described that may comprise a frame; first and second rails; and a trolley. The frame may support the first and second rails. The trolley may comprise a base, a first wheel assembly coupled to the base and in contact with the first rail, and a second wheel assembly coupled to the base and in contact with the second rail, wherein the trolley is movable between respective lower ends of the first and second rails and respective upper ends of the first and second rails via the first and second wheel assemblies contacting the first and second rails. The base of the trolley may comprise a proximal portion and a cantilevered portion extending away from the proximal portion to a free end, wherein the first and second wheel assemblies are coupled to the proximal portion and the cantilevered portion extends over the first and second rails.

Abstract: A surrogate component for a test system is described. The surrogate component may comprise: a body, comprising, a first shell comprising a plurality of exit holes; and a second shell coupled to the first shell, wherein the second shell comprises a first connection interface and a second connection interface; and a wiring harness, comprising: at least one data communication line coupled to the first connection interface and passing through one of the plurality of exit holes; and at least one power line coupled to the second connection interface and passing through the one of the plurality of exit holes.
