14.5.6.3 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 216). Up to three sub blocks (with two 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:
