1. A non-contact reflectometry system for testing a signal path comprising:
- a) an injection probe 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 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.

Abstract
Non-contact reflectometry for testing a signal path is described. The technique includes using capacitive coupling to inject a test signal into the signal path and extract a response signal from the signal path. Reflectometry techniques are used to determine characteristics of the signal path from the response signal. The technique is compatible with performing testing of a signal path carrying an operational signal.
