Abstract:
1. A network analysis device for improved measurement of resistance, comprising: an AC component to transmit and measure a signal for determining a resistance of a cable; a master unit comprising a master source impedance transmitter to a receiving device resulting in a first master impedance, a plurality of diodes and a plurality of output capacitors resulting in a second master impedance, and a plurality of shunt diodes resulting in a third master impedance, and at least one coupling connector for connecting the network analysis device at the master unit to the cable; a remote unit comprising a remote source impedance transmitter to a receiving device resulting in a first remote impedance, a plurality of diodes and a plurality of output capacitors resulting in a second remote impedance, and a plurality of shunt diodes resulting in a third remote impedance, and at least one coupling connector for connecting the network analysis device at the remote unit to the cable; and a correction component for improving the accuracy of the resistance of the cable by correcting for error in at least one of cable capacitance deviation from nominal, cable termination deviation from nominal, and nominal cable effects.
