• Question 31:

  What do deflections indicate to the time domain reflectometer user?

  A. They indicate splices, water in the cable, split pairs, and discontinuities or faults.
  B. Do not connect live circuit cables to the input of the time domain reflectometer. Connect the cable that is being tested to the cable connector on the front panel of the time domain reflectometer.
