Multi-SEM measurements
Multi-SEM measurements are SEM measurements with more than one sub block. In
these measurements, each sub block has its own power class definitions. In this case,
the power class is not indicated in the graphical result displays.
Example:
For example, in Figure 7-42 , "31 < P < 39" is indicated as the used power class is
defined from 31 to 39.
