Global span settings
The span of the signal to be monitored is configured in the general span settings (see
Chapter 6.3.2, "Frequency and span settings" , on page 447). Only ranges within this
global span are considered for the SEM measurement.
Multi-SEM configuration
In the Spectrum application 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 236). Up to 8 sub blocks (with 7 gaps) can be defined. For
each sub block, the familiar configuration settings concerning ranges, limit lines etc.
can be defined in individual tabs. In addition, settings on the sub blocks themselves
must be configured in the "Sub Block" tab of the "Spectrum Emission Mask" configura-
tion dialog box (see
Chapter 5.6.5.2, "Multi-sem (sub block) settings" , on page 246).
The following settings are available in individual tabs of the "Spectrum Emission Mask"
configuration dialog box.

5.6.5.1 Sweep List
Access : "Overview" > "Select Measurement" > "Spectrum Emission Mask" > "Sweep
List"
For SEM measurements, the input signal is split into several frequency ranges which
are swept individually and for which different limitations apply. You configure the indi-
vidual frequency ranges and mask limits in the "Sweep List" .
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 229.
