Interpreting Step TDR Results

A Step TDR trace looks different than a traditional pulse 

TDR. Essentially, the Step TDR allows you to roughly 

measure the impedance of the line over distance. This 

is extremely useful for detecting bridged taps because 

the extra cable causes a drop in the impedance of the 

line over the length of the bridge. The examples below 

should provide some guidance in determining the type 

of fault that has been detected by the Step TDR.

No Fault over 450 Feet of Cable 

The resistance gradually rises until reaching the end  

of the cable, where it jumps to an open.

Close-in Bridged Tap at 30 Feet 

The bridged tap causes a sudden drop in resistance, 

which then picks up again at the end of the bridge.
