Abstract

A miniature probe for measuring small voltage signals of a DUT includes a probe body having a flexible substrate and signal transmission lines running a longitudinally, and a first probe connection circuit located at a first end of the probe body and including exposed wires, SMT components coupled between the exposed wires and the signal transmission lines, respectively, and a local mechanical stiffener mounted adjacent the SMT components. The wires are connectable to the DUT for receiving the voltage signals. The probe further includes a second probe connection circuit located at a second end of the probe body, and including transmission line connectors coupled to the signal transmission lines, respectively, and a bent portion of the flexible substrate between the probe body and the transmission line connectors. The bent portion enables the transmission line connectors to exit the probe substantially axially, relative to the longitudinal length of the probe body.
