1 The cable pairs relevant to the results.
2 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.
4 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.
5 Use D U to change the maximum distance of the horizontal scale.
