GAO Comm (Toronto) has released new time domain reflectometer (TDR) cable fault locator which uses a double cursor display for zoom analysis. The new handheld TDR cable fault locator from GAO, model A0N00019, is lightweight, and features a compact size with a backlit LCD screen. The locator is especially for use in testing underground cables to find out impedance break points and locating and revealing cable damage and terminal impedance failures in hybrid fiber coaxial (HFC) systems.
This particular TDR cable fault locator is able to automatically locate and indicate the position of many kinds of RF cable faults such as short circuits, open circuits or high resistance points. Powered by 7.2 V 1.8 AH Ni-MH batteries, the GAO A0N00019 provides a continuous working period of 8 hours. It tests 25, 50, 75 and 100 ohm impedance cables with a length of up to 2 km with a high accuracy of ±1 m ±1%. Its impedance resolution is 5%.
