Question

Quizplus · Accepted Answer

A Time Domain Reflectometer (TDR) is a tool used to measure the length of a cable run and locate any faults or breaks in the cable. It sends a signal through the cable and measures the time it takes for the signal to reflect back, which can be used to calculate the length of the cable. A TDR is the most appropriate tool for determining cable length in this situation.  The other options (B) Multimeter, (C) OPM, and (D) Tone generator, are not designed for measuring cable length.
