Principle of operation

✅ The principle of operation of the TDR-410 reflectometer is to measure the running time of the signal (probing pulse) in the cable pair from the place of connection to the end of the cable or to the nearest damage and back.

✅ Probing pulses run in the cable at Vp speed (called propagation speed), which depends on the electrical parameters of the cable, and in particular on the material from which its insulation is built

✅ Based on the Vp value selected by the user and the measured pulse time, the reflectometer calculates the distance to the wave impedance disturbance and displays the image of the cable in the form of a reflectogram illustrating any discontinuities of wave impedance on the studied section.

Connecting the tested cable to the reflectometer

❌ Before connecting the reflectometer, make sure that power sources and other devices are disconnected from the tested cable.

✔ Make sure that the test track is open or compact at the opposite end (it is not terminated with a resistive terminator).

✔ The TDR-410 reflectometer should be connected to one from the ends of the tested cable. The tested cable shall be connected to the banana outputs of the TDR-410 reflectometer located in the upper part of the instrument housing directly or with the help of wires terminated with crocodile clamps, which are equipped with the device:

• A- Coaxial cable Red crocodile should be connected to the middle vein, black to the screen/braid.
• B- Shielded cable Red crocodile should be connected to the vein closest to the screen, black clamp to the screen.
• C- Steam twisted pair The test pair should be separated from the other pairs and the red and black terminals should be connected to the individual conductors of the test pair.
• D- Multicore cable- Crocodiles of measuring wires should be connected to any two conductors of the cable.
