Abstract

A method of characterizing a signal path comprising (i) generating 102 a reference spread-spectrum signal; (ii) coupling 104 the reference spread-spectrum signal into the signal path while the signal path is carrying an operational signal; (iii) receiving 106 a reflected spread-spectrum signal from the signal path generated in response to the reference spread-spectrum signal; and (iv) correlating 108 the reflected spread-spectrum signal with the reference spread-spectrum signal to produce a correlation result corresponding to a characteristic of the signal path.
