FDR Results
The FDR graphs distance on the X-axis and amplitude on the Y-axis
as the LST-1700 transmits signals down the cable and looks for RF
energy being reflected back. Reflections occur when there is a change
in impedance possibly caused by such things as cable damage, un-
terminated ports, or improper installation.
