11.5.6.3 Configuring a Multi-SEM Measurement
As of firmware version 1.91, and in the Spectrum application only, spectrum emissions
can be measured for multiple s ub blocks of channels (see chapter 5.6.4.5, "SEM with
Multiple Sub Blocks ("Multi-SEM")", on page 205). Up to three s ub blocks (with two
gaps) can be defined. For each s ub block, the familiar configuration settings concern-
ing ranges, limit lines and MSR can be defined in individual tabs (select the s ub block
using the <sb> suffix in the corresponding commands). In addition, settings on the s ub
blocks themselves must be configured.
Useful commands for multi-SEM measurements described elsewhere:
