To create or modify a library element containing parameters of a particular spectrum mask, select the Spectrum emission masks command from the Library pull-down menu or directly with CTRL+SHIFT+S.
A list of existing pre-defined spectrum emission mask will be selectable as shown in the figure below. This is an example of a LTE UE (Table 6.6.3.1-2 of 3GPP TS 36.101) where the limit for the spurious emission domain (outside ± 12.5 MHz) applies to frequencies above 1000 MHz:

When adding a new spectrum emission mask, enter the name (unique identifier) and description of its technical parameters.
Note 1: It is possible to quickly scroll up and down and see the differences in the masks.
Note 2: It is possible to create a mask from the workspace and export it to your library environment
