7.2.7.5 SEM Configuration
Access : "Overview" > "Select Measurement" > "Spectrum Emission Mask"
The SEM measurement is started immediately with the default settings.
The remote commands required to perform these tasks are described in Chap-
ter 11.6.7, "Measuring the Spectrum Emission Mask" , on page 659.
Global span settings
The span of the signal to be monitored is configured in the general span settings (see
Chapter 7.4.2, "Frequency and Span Settings" , on page 302). Only ranges within this
global span are considered for the SEM measurement.
Multi-SEM configuration
In the Spectrum application 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 3 sub blocks (with 2 gaps) can be defined. For each sub block, the
familiar configuration settings concerning ranges, limit lines etc. can be defined in indi-
vidual tabs. In addition, settings on the sub blocks themselves must be configured in
the "Sub Block" tab of the "Spectrum Emission Mask" configuration dialog box (see
"Multi-SEM (Sub Block) Settings " on page 179).
The following settings are available in individual tabs of the "Spectrum Emission Mask"
configuration dialog box.
