3. The R&S Cable Rider ZPH opens a submenu to select the measurement mode.
4. Select the "Spectrum Emission Mask"" menu item.
The R&S Cable Rider ZPH 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 Cable Rider ZPH. Correct measurement
results are therefore only possible if the frequency ranges of the SEM are inside the
current span of the R&S Cable Rider ZPH.

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