ABSTRACT:
A differential electrical test probe tip for sensing a plurality of electric signals and generating a differential signal including an elongate common substrate having a two signal test points at one end and a differential amplifier at the second end. Two transmission lines are on the common substrate, each connecting a respective signal test point a signal input of the differential amplifier. The characteristic impedances of the two transmission lines are substantially equal. In one preferred embodiment, the common substrate is a flexible substrate. In one preferred embodiment an over-mold, which may have gaps therein, at least partially encloses the common substrate, the first transmission line, and the second transmission line.
