How does a time domain reflectometer work
http://tscm.com/riprcop.html WebA time domain reflectometer setup is shown in Figure 3. The step generator produces a positive-going incident wave that is applied to the transmission system under test. The step travels down the transmission line at the velocity of propagation of the line. If the load impedance is equal to the characteristic impedance of the line,

Webcontrol maintenance troubleshooting time. The loca-tion of the fault was found inside the reactor vault at the flux detector assembly. This information was extremely useful since it allowed preplanning for material to be ordered to site in preparation for the repair work. Preplanning is important to minimize outage time and maximize productivity. WebTime Domain Reflectometer starts its operation by sending impulse or step signals or energies. Then it observes the reflected energy or the signals subsequently. The discontinuity of impedance is measured and analyzed by the reflected pulses of energies as the amplitude, magnitude, and waveforms help in analyzing.
