There is disclosed a contactless test probe using an ionized gas discharge for making electrical contact with the device under test (DUT). In one embodiment the ionized gas discharge is at or below atmospheric pressure thereby reducing the complexity of the control environment. In one embodiment, the atmospheric gas discharge, i.e. the electrical probing medium, is created and controlled by a micro-hollow cathode. In a further embodiment an extension gate is used to extend/retard the range of the high-density discharge.
