Abstract:
1. A system, comprising: a signal transmitting system that transmits first and second test signals into a cable each time a test is initiated, wherein, a signal receiving system that receives first and second return signals from the cable that correspond to the first and second test signals, wherein the first and second return signals are used during each test an analog-to-digital converter (ADC) that converts the first and second return signals to first and second digital signals; a time domain reflectometry (TDR) system that receives the first and second digital signals from the ADC and signals from a memory, wherein the TDR system uses the first and second digital signals and the signals from the memory to determine at least one of a state of the cable or a connectivity of the cable; and a controlling system that controls at least one of the signal transmitting and receiving systems, the ADC, and the TDR system, the controlling system including a controller and one or more state machines that are all used to control operation for the TDR system.
