describes an example of the screen.
1
The cable pairs relevant to the plot.

Frequency range in MHz. Use U D to switch between scales. To switch to the next lowest
or highest range, use L R to move the cursor beyond the left or right side of the plot.
3
The ELFEXT level, frequency, and margin at the cursor's position. The cursor aligns to the
frequency that produced the worst margin. Margin is the difference between the limit and
measured values plotted at the cursor's position. If you move the cursor beyond the highest
test frequency specified by the selected test standard, the readout shows the ELFEXT
value at the cursor's position.
4
The limits for ELFEXT, as defined by the selected test standard. A crosshair is shown if the
limit is defined for only one frequency.
5
Decibels of ELFEXT for the cable pairs.
6
The calculated ELFEXT for the cable pairs.
