It can be used for the same cable testing after the
calibration.
Application
：
TDR test is the use of pulse reflection method, to transmit pulse signal for tested cable,
when cable is disconnected or short-circuited, reflected pulse generated, the tester receive and deal with
the reflected wave,
measurement results displayed on the screen. TDR cable test can test cable length
and short circuit, help engineer quickly find the cable’s problem location. It is more convenient and
efficient to repair the faulty cable.
Note
：
The TDR reflect signal could be affected by the cable quality/ cable’s not well
connected etc to cause the different TDR measurement. The TDR measurement is for reference
only.
