Patent ID: 6937944

Claim:
A method for creating Baseline FDR measurements to be used for determining integrity of a cable under test utilizing a frequency domain reflectometry (FDR) cable testing system, said method comprising the steps of: (1) coupling the FDR cable testing system to a connecting end of the cable under test, wherein it is assumed that the integrity of the cable under test is not compromised; (2) generating signals from the FDR cable testing system in order to obtain a baseline FDR measurement for the cable under test, comprising the steps of: (a) transmitting at least one input signal from the FDR cable testing system to the cable under test, and to a mixer; (b) receiving a reflected input signal from the cable under test; (c) mixing the at least one input signal and the reflected input signal in the mixer to thereby generate a DC signal; and (3) storing the baseline FDR measurement for the cable under test.
