Description

The cable pair relevant to the plot.

Frequency range in MHz of the attenuation test.

Margin is the difference between the limit and measured values plotted at the cursor’s position. Use LRto 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 attenuation value at the cursor’s position.

The measured attenuation for the cable pair.

The attenuation limits, as defined by the selected test standard. A crosshair is shown if the limit is defined for only one frequency.
