Model 2901C is an inexpensive alternative to the traditional "waveform" TDR. Model 2901C digital TDR will identify cable damage causing a major impedance change. Any metallic paired cable can be tested quickly and easily without sacrificing accuracy.

Test all types of aerial and underground transmission cable including coaxial, twisted pair, communications and power cables. Cable in conduits and behind finished walls can all be tested.

Measure cables on the reel or already installed. The oscilloscope output feature allows the "signature" of the cable to be viewed.

Low cost, compact size, and simple operation combine to make the Model 2901C a must for every repair/maintenance technician or crew.
