Distance To Fault

From Anritsu Company
 

 
Distance To Fault (DTF) is a performance verification and failure analysis tool used for antenna and transmission line service and maintenance. It uses the Frequency Domain Reflectometry (FDR) measurement technique. FDR is a transmission line fault isolation method which precisely identifies signal path degradation for coax and waveguide transmission lines. Although the acronyms are similar, FDR technology is different from traditional Time Domain Reflectometry (TDR) techniques. The FDR technique uses a swept RF signal instead of TDR DC pulses. FDR is far more sensitive than TDR and can precisely locate faults and degradation in system performance, not just DC open or short circuit conditions. This dual role of predicting future failure conditions and isolating existing problems makes DTF an important part of service and maintenance on transmission lines.
