Progression: Construction Coordinator I - II Exam Answered Correctly. A chain trencher A return path sweep-and-alignment system is used to adjust which of the following? Anomalies, such as echoes and blind spots, can hide cable faults or cause a technician to misinterpret the signature of a time domain reflectometer (TDR) waveform. What causes an echo on a waveform TDR? As the RF signal travels on the coaxial cable, one portion of the signal may be attenuated more than the others. ...
