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