ABSTRACT:
A method for improved cable resistance measuring is provided including coupling a measurement test device including a master unit and a remote unit, via at least one connector, to at least one network cable and determining a terminating impedance using field calibration. The method additionally including transmitting an AC signal across the network cable for determining a resistance of the network cable, and measuring a length of the network cable. The method still further including measuring a capacitance of the network cable, and measuring an impedance of the network cable terminated by the measurement test device. The method additionally including extracting the resistance of the network cable from the impedance measurement, and correcting for error in at least one of capacitance, termination resistance, and nominal cable effects for a corrected resistance value.
