ment. You only have to activate the mode for one range, the others are adapted
automatically.
8. If necessary, change the settings for the reference power to which all SEM results
refer in the "Reference Range" tab.
9. To indicate the determined peaks in the display during an SEM measurement,
select "Overview" > "Analysis" > "Show Peaks".
10. To save the current SEM measurement settings to a file to re-use them later, save
a settings file as described in "How to save a user-defined SEM settings file"
on page 270.
11. Start a sweep.
The determined powers and limit deviations for each range are indicated in the
Result Summary. If activated, the peak power levels for each range are also indica-
ted in the Spectrum diagram.
12. To save the Result Summary, export the results to a file as described in Chap-
ter 7.6.6.2, "How to Save SEM Result Files" , on page 271.
To perform an MSR SEM measurement
1. Select the "MSR Config" softkey.
2. Select the band category that determines the digital standards used in the mea-
surement setup (see "Band Category" on page 261).
3. Define the bandwidth that contains all relevant carrier signals to be measured.
4. For measurements with GSM/EDGE, LTE FDD and W-CDMA carriers (BC2),
define whether a GSM/EDGE or an LTE FDD carrier, or both, are located at the
edge of the bandwidth.
5. Select the "Apply to SEM" button.
The sweep list is configured according to the MSR specification, with the required
number of ranges and defined limits.
6. Start a sweep.
The determined powers and limit deviations for each range are indicated in the
Result Summary. If activated, the peak power levels for each range are also indica-
ted in the Spectrum diagram.
7. To save the Result Summary, export the results to a file as described in Chap-
ter 7.6.6.2, "How to Save SEM Result Files" , on page 271.
To perform a Multi-SEM measurement
1. Define the span of the signal to be monitored in the general span settings.
2. Select the "Multi-SEM Config" softkey.
3. Define the number of sub blocks (up to 8) that contain the relevant carriers.
