Figure 118, Cable Testing Interface
The TDR Test uses pulse reflection to transmit pulse signals
through a tested cable. When the cable is open circuit or short-
circuit, a reflected pulse is generated,
The Tester receives the reflected wave and displays the
measurement results on the screen. The TDR test can identify
open and short circuits and quickly identify the location where
the cable has a problem. It is more convenient and efficient to
repair a faulty cable rather than replace it.
The TDR reflect signal could be affected by the cable
quality, cable not being connected, etc., which can
cause differences in TDR measurements. The TDR
measurement should be used for reference only.
