If "Symmetrical Setup" mode is active when "Fast SEM" mode is activated, not all
sweep list settings can be configured symmetrically automatically (see also
Any other changes to the sweep settings of the combined range are applied to each
included range and remain changed even after deactivating "Fast SEM" mode.
Example
Figure 5-42: Sweep list using Fast SEM mode
In
, a sweep list is shown for which Fast SEM is activated. The formerly five
separately defined ranges are combined to two sweep ranges internally.

Multi-standard radio (MSR) SEM measurements
Multi-standard radio (MSR) measurements allow you to perform SEM tests on signals
with multiple carriers using different digital standards. MSR measurements are descri-
bed in the specification 3GPP TS 37.141. Various typical combinations of standards for
base station tests are described, e.g. LTE FDD and W-CDMA carriers. By performing
an MSR SEM measurement you can determine if or how the different carriers affect
each other, i.e. if unwanted emissions occur. On the R&S
FSV/A, the MSR SEM mea-
surement is a standard measurement as for single carriers. The MSR settings merely
provide a convenient way of configuring the sweep list for all required ranges according
to the specification quickly.
Refined settings allow the R&S
FSV/A to calculate the SEM limits according to stan-
dard 3GPP 37.141 V12.2.0, which distinguishes between base station configurations
and power values.
