10.6.7.3 Configuring a Multi-SEM Measurement
In the Spectrum application only, spectrum emissions can be measured for multiple
sub blocks of channels (see
"SEM with Multiple Sub Blocks ("Multi-SEM")"
on page 169). 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 indi-
vidual tabs (select the sub block using the <sb> suffix in the corresponding com-
mands). In addition, settings on the sub blocks themselves must be configured.
Useful commands for multi-SEM measurements described elsewhere:
