A system for positioning an electronic test head of a test system with respect to an electronic device handler. A housing is provided having a vertical shaft. A positioner assembly moves vertically with respect to the shaft and provides substantial movement in the horizontal plane with six degrees of freedom. The positioner assembly includes a section for attaching the test head. A counterbalancing assembly is coupled to the positioner assembly and has a counterweight to provide a substantially weightless condition to the positioner assembly with the test head attached.
