14.5.7.3 Configuring a Multi-SEM Measurement
In the Spectrum application only, spectrum emissions can be measured for multiple
sub blocks of channels (see
Chapter 7.6.4.5, "SEM with Multiple Sub Blocks ("Multi-
SEM")" , on page 246). 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 (select the sub block using the <sb> suffix in the correspond-
ing commands). In addition, settings on the sub blocks themselves must be configured.
Useful commands for multi-SEM measurements described elsewhere:
