2. Time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Time-domain_reflectometer

   A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses. It can be used to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable ), [ 1 ] and to locate discontinuities in a connector, printed circuit board ...

3. Optical time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Optical_time-domain...

   An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test.

4. TDR moisture sensor - Wikipedia

   en.wikipedia.org/wiki/TDR_moisture_sensor

   A spatial TDR moisture sensor employs time-domain reflectometry (TDR) to measure moisture content indirectly based on the correlation to electric and dielectric properties of materials, such as soil, agrarian products, snow, wood or concrete.

5. Reflectometry - Wikipedia

   en.wikipedia.org/wiki/Reflectometry

   In time-domain reflectometry (TDR), fast pulses are emitted, and the magnitude, duration and shape of the reflected pulses is analyzed. Frequency-domain reflectometry (FDR): [5] [6] this technique is based on the transmission of a set of stepped-frequency sine waves from the sample. As with TDR, these waves propagate to the sample and are ...

6. Spread-spectrum time-domain reflectometry - Wikipedia

   en.wikipedia.org/wiki/Spread-spectrum_time...

   Spread-spectrum time-domain reflectometry (SSTDR) is a measurement technique to identify faults, usually in electrical wires, by observing reflected spread spectrum signals. This type of time-domain reflectometry can be used in various high-noise and live environments. Additionally, SSTDR systems have the additional benefit of being able to ...

7. Reflections of signals on conducting lines - Wikipedia

   en.wikipedia.org/wiki/Reflections_of_signals_on...

   A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...

   They watch us all the time! But sometimes they still need some guidance when it comes to walking . You want to create a routine for your pup so they'll recognize the signs that it's time to go out.

9. Avaya ERS 5500 Series - Wikipedia

   en.wikipedia.org/wiki/Avaya_ERS_5500_Series

   The Switches have an integrated time-domain reflectometer (TDR) built into every copper port, providing diagnostic monitoring and troubleshooting capabilities of the connected cables allowing for the troubleshooting of cable defects (crimped, cut, shorted or damaged cables) from the telnet, SNMP, web and console management interfaces. This test ...
