Application: TDR test is the use of pulse reflection method, to transmit pulse signal for tested cable,
when cable is open circuit or short-circuit, reflected pulse is generated, the tester receives and deals with
the reflected wave, measurement results displayed on the screen. TDR can test cable open circuit 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.

3.3.26 BNC attenuation test (* Optional )

Introduction: Through hardware high-speed sampling and processing technology, the coaxial cable
transmission attenuation value can be tested in real time, which can be used to detect the attenuation of
the coaxial cable through long-distance transmission and the attenuation value of different cables but at
the same distance, and can detect the quality of coaxial cable.
Test Methods:
1. Connect the two alligator clip cables to the CVBS IN port and CVBS OUT port separately. Two
crocodile clips red to red and black to black clip together, then click "calibration" to calibrate it.
