Overview
In this example, an implementation of Time Domain Reflectometry (TDR) is shown. A NI Arbitrary Waveform Generator and NI Digitizer are used. The application measures the distance between the origin of the sent signal and the first impedance change in a coaxial cable (open or short termination condition).
Description
The IVI Time-domain reflectometry or TDR is a measurement technique used to determine the characteristics of electrical lines by observing reflected waveforms. Time-domain transmissometry (TDT) is an analogous technique that measures the transmitted (rather than reflected) impulse. Together, they provide a powerful means of analysing electrical or optical transmission media such as coaxial cable and optical fiber. Hardware is necessary for this application.

Hi Josevolquez
I'm currently doing the TDR measurement using the module made by you. From the folder i cannot found the TDR Demo Script.pdf. Can you help to povide pdf file
