Plus Test Set
Detecting Bridged Tap in Autotest
With the Step TDR feature enabled, the unit also
provides a bridged tap detection test in the autotest.
This test can be selected by editing the custom script
and enabling the Bridge Tap test. When the custom
autotest script, the unit will perform a Step TDR test
over the length of the cable and determine if a bridged
tap exists. If so, the autotest will fail and provide the
distance to the bridged tap (as shown below).
If no bridged taps are detected, the autotest will pass
and show no bridged taps (as shown below).
In some cases, it may be that there is a disturber on the
line that may or may not be bridge tap (e.g., a splice,
split, or resistive imbalance). In that case, a bridge tap
will be shown with the hazard icon instead of with
the “X” mark.
