Overview

Application Area

The optimum solution for rapid troubleshooting of cable networks – extremely easy to operate, compact and cheap TDR tester.

TDR-TA3.3T – a single-channel cable fault locator, designed to determine the nature and location of the cables faults (open, short, sleeve, cable splice, parallel challenge, Pupin coil).

The small size and weight make the TDR-TA3.3T especially convenient for working in confined spaces cable wells. High precision characteristics allow to measure near and far zones.

Sphere of application

TDR-TA3.3T is intended to measure on cables of the following types:

  • signal and control cables;
  • power cables;
  • aerial cable lines;
  • computer networks ;
  • TV and radio cable lines.
