7.2.6.5 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 Chapter 8.6.6,
"Measuring the Spectrum Emission Mask", on page 561.
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 376). 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 297). 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. 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 307).
The following settings are available in individual tabs of the "Spectrum Emission Mask"
configuration dialog box.
● Sweep List ............................................................................................................302
● Multi-SEM (Sub Block) Settings ...........................................................................307
● Reference Range..................................................................................................308
