Abstract

Abstract A probe for use with microelectronic circuitry characterized by a screw-actuated clamping mechanism which affords the probe structure diminished portions while providing superior pincoupling and locking ability. The probe is of general utility; however, it includes design features which specifically complement its use in association with digital circuitry. In this respect, a logic pack of the type used in the circuit to be monitored is positioned in the probe housing and electrically connected in the input thereof. The logic pack is interchangeable to permit the characteristics of the probe to be directly matched to the circuit being monitored.
