SEM Display
The SEM (Spectrum Emission Mask) display measures out-of-band emissions immediately outside the
channel bandwidth that result from the modulation process and non-linearity in the transmitter. The
Spectrum Emission Mask display allows you to define up to six pair of masks, or offsets, that specify the
limits for out-of-band emissions and performs a pass/fail tests of the signal against the defined offsets
and limits.
To show the Spectrum Emission Mask display:
1. Recall an appropriate acquisition data file.
2. Select Displays or select Setup > Displays.
3. In the Select Displays dialog, select RF Measurements or WLAN Analysis in the Measurements box.
4. In the Available displays box, double-click the SEM icon or select the icon and click Add. The SEM
icon will appear in the Selected displays box and will no longer appear under Available displays.
5. Click OK to show the Spectrum Emission Mask display.
6. Press the Replay button to take measurements on the recalled acquisition data file.
