Data Setup editor to configure payload bits. You can also load, save, and create custom bit patterns.Custom Modulation
Use this drop-down menu to select a modulation type from several supported formats. A single data segment using that modulation type appears in the segment list below. Click the cell in the Constellation column to open the Constellation Setting window, providing a graphical display and editing features. Quick setups enable you to configure complex signals for signal generation, equivalent to 89600B VSA setups in signal analysis.
DVB-S2 and DVB-S2X quick setups also add a PLHEADER segment before the data segment, as defined in the standard.
