Having the ability to detect faulty conditions in a wire bundle only satisfies a portion of the challenges in maintenance environments where platforms are becoming more complex with fewer available resources. The technicians are forced to predict potential fault locations which often lead to the disassembly of more areas than required. The extended amount of repair time increases costs and decreases operational readiness.

The Eclypse ESP and ESP+ Reflectometers are hand-held, non-intrusive analyzers that find the precise location of a short or open circuit within a cable. The ESP family of portable Standing Wave Reflectometer (SWR) meters provides the user the means to determine the nature and location of discontinuity in a cable by monitoring the impedance while varying the frequency of an oscillating signal that was injected into the cable from one end. The ESP and ESP+ devices are user friendly, menu driven meters designed to provide the operator explicit displays describing the type ,(open or short), and location from the measurement point to the wiring fault. Step-by-step instructions guide the operator through all of the menu operations while the alphanumeric screen displays the output.

The ESP can operate successfully in temperatures ranging from -20°C to +60°C with a specified range of 1,000 feet. The device possesses the ability to store 99 programmable settings for various cable and conductor types, including coaxial, triaxial, multistrand single conductor, and twisted pair. The ESP+ Reflectometer retains all of the features of the original, but also contains a flash memory that allows the operator to store 32 test waveforms that can be uploaded to any personal computer for comparison and analysis.
