Title :
Sweep-frequency measurement of structural return loss by a carrier-burst method

Abstract :
Errors due to hybrid unbalance and reflections from connectors and terminations are eliminated by using a burst of carrier as the test signal. A sampling oscilloscope extracts that part of the signal which is proportional to the reflection from the cable alone.
