Patent ID: 8549909

Claim:
A modular TDR probe assembly comprising: a first elongated portion having a first impedance wherein the first elongated portion further comprises a first central conductor and a first outer conductor; a second elongated portion having a second impedance, wherein the second elongated portion further comprises a second central conductor and a second outer conductor; a dielectric insert comprising a solid dielectric material, a dielectric insert first end, a dielectric insert second end, and a bore passing through the dielectric insert between the first end and the second end; a terminal pin comprising a conductive material having a terminal pin first end and a terminal pin second end configured to be disposed at least partially within the dielectric insert bore with the terminal pin first end extending from the dielectric insert first end and the terminal pin second end extending from the dielectric insert second end; and an elbow comprising a first end and a second end configured to substantially enclose the dielectric insert and terminal pin disposed within the elbow, wherein the elbow first end is configured to connect to the first elongated portion and thereby place the first center conductor in electrical communication with the terminal pin first end, and the elbow second end is configured to connect to the second elongated portion and thereby place the second central conductor in electrical communication with the terminal pin second end.
