Multi-SEM configuration
As of firmware version 1.91, and in the Spectrum application only, spectrum emissions
can be measured for multiple sub blocks of channels (see
chapter 5.6.4.5, "SEM with
Multiple Sub Blocks ("Multi-SEM")" , on page 205). Up to three sub blocks (with two
gaps) can be defined. For each sub block, the familiar configuration settings concern-
ing ranges, limit lines and MSR can be defined in individual tabs. In addition, settings
on the sub blocks themselves must be configured in the "Sub Blocks" tab of the "Spec-
trum Emission Mask" configuration dialog box (see
chapter 5.6.5.2, "Multi-SEM (Sub
Block) Settings " , on page 215).
The following settings are available in individual tabs of the "Spectrum Emission Mask"
configuration dialog box.

5.6.5.1 Sweep List
For SEM measurements, the input signal is split into several frequency ranges which
are swept individually and for which different limitations apply. In the "Sweep List" tab
of the "Spectrum Emission Mask" dialog box you configure the individual frequency
ranges and mask limits.
If you edit the sweep list, always follow the rules and consider the limitations described
in
chapter 5.6.4.1, "Ranges and Range Settings" , on page 199.
