The cable pairs relevant to the results.

The distance along the cable under test. The 0 at the left of the scale represents the
location of the main test tool.
3
Magnitude of crosstalk on the cable pair. A peak over 50 indicates a crosstalk level that
exceeds the limit specified by the selected test standard. Crosstalk levels are adjusted
to compensate for cable attenuation.

The Cursor Readout shows the distance to the crosstalk source at the cursor’s
position. The cursor aligns to the highest crosstalk peak. Use
L R
to move the cursor
left or right.

Use
D U
