Loop Mapper Test
Result Summary
The Result Summary tab allows you to
view results of the Loop Mapper test in
graphical and text form.
TDR Graph
The TDR Graph tab allows you to view
results of the high resolution TDR test
methodology used in the Loop Mapper
test. TDR first attempts to find the
length of the circuit and then searches
all ranges from shortest to longest for
significant events. Upon completion,
the test selects the nearest major
event, sets the range to match, and
aligns the cursor with the event.
To make TDR adjustments via the keypad:
1. Press
to change the mode button (top-right corner of the pane)
and function of the up/down arrow keys.
