2. Select the "Meas Mode" softkey.
3. The R&S Spectrum Rider opens a submenu to select the measurement mode.
4. Select the "Spectrum Emission Mask"" menu item.
The R&S Spectrum Rider starts to measure the spectrum emission mask.
Note that the frequency range of the actual measurement depends on the start and
stop frequency you have set on the R&S Spectrum Rider. Correct measurement results
are therefore only possible if the frequency ranges of the SEM are inside the current
span of the R&S Spectrum Rider.

Markers in the SEM measurement
In addition to the normal marker functionality of the R&S Spectrum Rider, the SEM
measurement provides special markers labeled P1 to Px.
The R&S Spectrum Rider activates and positions these special markers automatically
after displaying the trace. Each of these markers marks the peak level in each SEM
