Reflectometer

About[]

A time-domain reflectometer (TDR) is an electronic instrument used to characterize and locate faults in metallic cables (for example, twisted wire pairs, coaxial cables). It can also be used to locate discontinuities in a connector, printed circuit board, or any other electrical path. The equivalent device for optical fiber is an optical time-domain reflectometer.

Some instruments commonly designated Reflectometer are:

  • Vector Network Analyser (VNA)
  • Spectrophotometer: in optics, an instrument for measuring the reflectivity or reflectance of reflecting surfaces
  • Optical time domain reflectometer
  • Reflectometer (electronics): In electronics, a directional coupler containing matched calibrated detectors in both arms of the auxiliary line, or a pair of single-detector couplers oriented so as to measure the electrical power flowing in both directions in the main line
  • Time-domain reflectometer

Maintenance Data[]

Listed are recommended maintenance cycles that can be loaded within local computerized maintenance management systems. These cycles can also be used to estimate average monthly cycle inspections, PMs, and calibrations with average technician hours. This device is corrective maintenance only. Disclaimer: It is recommended to consult OEM cycles.
