Lexxi T1660
TDR Time Domain Reflectometer/ Network Analysis/ Cable Test
Radiodetection’s Lexxi T1660 provides an unrivalled combination of performance, usability and economy. Radiodetection
has created Lexxi T1660 by taking the easy-to-hold ergonomics familiar to users of the Riser Bond Model 1550 and
Bicotest Lexxi T810 and installing a unique TDR engine and a 3.5” color back-lit display.
The result is a cable tester whose 1% distance accuracy and resolution gives technicians the tool they need to find faults quickly and accurately. Added to this is the Lexxi T1660’s great value that allows more technicians to be equipped.
The Lexxi T1660 is suitable for analyzing all metallic cables consisting of a least two metallic elements, one of which can be
the armouring or the screen. Cable types include CATV, twisted pair telecom, Ethernet and even LV power cables.
The Lexxi T1660 is shipped with a set of 100Ω crocodile clip Twisted Pair connection cables as standard. A range of
optional plug-in modules make it adaptable to the requirements of a wide variety of industries and applications, with the Blocking Filter module allowing safe analysis of live 3-phase mains cables. Radiodetection’s Lexxi T1660 offers innovation
and economy, enabling a step-change in productivity.
