  • Patent number: 7031856
    Abstract: A system and method for automatically determining a dielectric constant for a cable of known length for use in a Time Domain Reflectometer (TDR) are disclosed. The TDR mode is set to time mode. A waveform for the cable is acquired from the TDR. The waveform indicates the time of a round trip distance of a signal through the cable. The length of the cable is entered via a programmed operator entry. A Velocity of Propagation (VOP) is calculated based on the length of the cable and the time of the round trip distance. The dielectric constant is then calculated based on the calculated VOP.
    Type: Grant

  • Patent number: 6448781
    Abstract: A method for analyzing cable faults includes dividing a waveform into a plurality of segments. The waveform is representative of a reflected signal created by applying a stimulus signal to a cable, and the slope at any point on each respective segment of the waveform falls within a respective specified range. The method further includes determining a longest segment from the plurality of segments, and identifying a predicted location of the fault based, at least in part, on the location of the longest segment.
