AEMC CA7026 2127.81 Fault Mapper Pro Telephone Coax Graphical Cable Tester

The AEMC CA7026 Fault Mapper Pro Cable Tester is a graphical hand held TDR (Time Domain Reflectometer) engineered to identify and locate faults on communication and power cables, with access to only one end.

The CA7026 measures cable length, and displays the distance to cable faults and terminations to a maximum range of 11,700 feet – 3500 meters, on almost any type of cable of 2+ conductors. The CA7026 shows a reflection profile of the cable being tested as an oscilloscope like waveform on a 128 x 64 pixel graphical LCD. A movable cursor can be aligned with points on the trace, and the distances displayed will automatically update the cursor position.
