A sanity check on the unwanted emission calculation can be done by using the <Test Rel. Unwanted> emission function in the menu bar of SEAMCAT, by clicking on the icon of the toolbar ( ) or by pressing <CTRL+SHIFT+U>. The definition of unwanted emissions mask can be checked by calculating the actual unwanted emissions for given mask in a given VLR bandwidth applying a certain ILT-VLR frequency offset:

This feature allows to directly extract the unwanted emission by entering the frequency separation, the receiver bandwidth and the spectrum mask as shown in Figure 56.
