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.
Products & Services
Optical time domain reflectometers (OTDR) measure the elapsed time and intensity of light reflected along an optical fiber. They are useful tools for locating problems in an optical network as they can compute the distance to breaks or attenuation.
Fault detectors and recorders are electric power instruments that detect and/or record electrical faults that may happen in power lines. A fault recorder keeps a log about the time, location, intensity of the fault.
Vector network analyzers are instruments that measure the complex transmission and reflection characteristics of two-port devices in the frequency domain.
Fiber optic fault locators shine red laser light through jacketed fibers to identify breaks, bends, faulty connectors, splices and other causes of signal loss.
Waveguide pressure windows are used to seal waveguides at high pressure and prevent contaminants from entering the system.
