Abstract:
1. A non-contact reflectometry system for testing a signal path comprising: a) an injection probe comprising a first conductive body shaped to create electrical capacitance between the first conductive body and the signal path when placed in near proximity to the signal path and configured to inject a test signal into the signal path via capacitive coupling to the signal path when placed in near proximity to a first point on the signal path; b) an extraction probe comprising a second conductive body shaped to create electrical capacitance between the second conductive body and the signal path when placed in near proximity to the signal path and configured to extract a response signal from the signal path via capacitive coupling to the signal path when placed in near proximity to a second point on the signal path; and c) a reflectometry instrument operatively coupled to the injection probe and to the extraction probe and configured to generate the test signal, accept the response signal, and determine a signal path characteristic from the response signal.
