The TDR-400 is a handy, light impulse reflectometer, processor controlled, with
LCD display for check and locate faults in telecommunication and power cables.
Measuring principle:
The measuring pulse fed into the cable will reflected by in homogeneity of the cable
impedance (cable faults) and showed on the display. The distance and the kind of the fault
can be determined out of the shape and the time setting of the reflection (Practical
experience can be obtained by test measurements). If the cable is terminated with a
resistance equal to the impedance of the cable, no reflexion occurs when the cable is
faultless. In the case of breaks, contact faults in sleeves, short circuits or taps/splitter in the
sector to be tested, the distance to the cable beginning can be determined by the pulse
echo. If wide pulses are used for the measurement, the echoes are stronger, but faultless
taps/splitter cause then strong echoes.
Propagation factor
The Propagation factor (nvp-value) declares the velocity of electrical signals in the cable in
relation to the speed of light. The propagation factor of the cable under test must always
preset before the length measurement. If the propagation factor is unknown, a
approximate value is set and the fault is determined from both ends of the cable.
