– Click “New”, enter the name and channel spacing then click “Save”.

– Click on “New” inside the MCS to define each modulation separately. Fill out the fields in the “General”, “Switching”, “ATPC”, “RTPC” tabs, respectively and click “Save”.

– Apply the same for the rest of the modulation schemes and once done with all, click “Save”
