Loop Mapper Test
Loop Mapper Test
The LoopMapper test allows you to easily identify faults in the cable with
increased resolution using time domain reflectometry (TDR) and
frequency domain reflectometry (FDR). This test is extremely useful in
locating bridge taps and the end of the cable. Faults such as open ends and
shorted ends can be easily found using the enhanced resolution of the FDR
test.
Note:
This test is only available if LoopMapper is enabled in the software options.
Test Setup
The
Test Setup
tab allows you to configure parameters for the Loop
Mapper test.
