How can I reduce Distance Errors in the TDR?

Viewed 119 Times
  1. Place the Cursor at the Beginning of where the trace deviates from the horizontal reference line, NOT at the center of the fault.
  2. Try to get closer to the fault. Distance errors are measured in Percentage. A 1% error is:
    1. 10 ft in a fault shown 1000ft away
    2. 1 ft in a fault 100 ft away
  3. Shoot the fault from both ends.
