3. In the "Sweep List" dialog box, define the limit line for each range using the "Abs
Limit Start" and "Abs Limit Stop" settings.
The limit values are absolute values for the absolute power level.
4. Set the "Limit Check" setting to "Absolute" to activate the limit check.
5. Close the "Sweep List" dialog box.
The limit line and the result of the limit check are displayed in the diagram and the
result table displays the largest deviations from the limit for each range.
6. To reduce the number of displayed delta values, change the margin (threshold) for
peak detection in the list evaluation. By default, this value is very high (200 dB), so
that initially all peaks are detected.
In the "Spurious" menu, press "List Evaluation > Margin" and enter a value in dB.
Only delta values that exceed this margin are displayed in the result table.
