Used Power Classes
Defines which power classes are considered for the SEM measurement. Limits can be
defined only for used power classes. It is only possible to select either one specific
power class or all of the defined power classes.
If "All" is selected, the power class that corresponds to the currently measured power
in the reference range is used for monitoring. The limits assigned to that power class
are applied (see
"Abs Limit Start/Stop <n>" on page 213 and "Rel Limit Start/Stop <n>"
on page 213).
