1
The cable pair relevant to the plot.
2
Frequency range in MHz of the RL test. Use
U D
to change the frequency scale.
3
The RL 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. Use
L R
to move the cursor left or right. If
you move the cursor beyond the highest test frequency specified by the selected test
standard, the readout shows the RL value at the cursor’s position.
4
The limits for RL, as defined by the selected test standard. The limit line is dashed at
frequencies where the attenuation is less than 3 dB.
5
Decibels of RL for the cable pair.
6
The measured RL for the cable pair.
