A non intrusive circuit tracer for positively identifying a conductor at ition remote from a point of injection of a test signal.

At another point along the conductor signal is sampled and synchronously demodulated first with respect to the tracer frequency and then with respect to the rate of alternation of the tracer frequency between conductors.
