Abstract
A device for testing data communications cabling. The device consists of a signal generator that can generate a test signal to test the data communications cabling and a receiving component that can receive a reflected signal produced by reflection of the test signal from the data communications cabling including any reactive point source disturbance that may exist on the cabling. The receiving component can determine characteristics of the reflected signal by analyzing the phase rotation and amplitude of the reflected signal. The device can also include a cancellation generator that can generate a cancellation function based on the characteristics of the reflected signal. The cancellation function can substantially negate a portion of the reflected signal.
