Item Description
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. Use
L R to move the cursor left or right.
5
Use D U to change the maximum distance of the horizontal scale.
