2 Working principles
TDR-410 measures the time course of the signal (the probe pulse) in a pair from connecting the cable
to the cable end or the nearest damage and back.
Probe pulses in the cable run at a speed Vp (the speed of propagation), which depends on the elec-
trical parameters of the cable, in particular the material from which the insulation is made.
A reflectometer calculates the distance to the disturbance of wave impedance path and displays the
cable's diagram showing any impedance discontinuity in the studied area based on Vp values select-
ed by a user and and measured the course time of the pulse.
