M6100 >> Modulator >> Roll Off Signaling
• standard : (2 bits : "10") roll off signaling value is used for roll off = 20%;
• reserved : (2 bits: "11") roll-off signaling value is "reserved" (11) is used for roll off < 20%.
Some DVB-S2 receivers can use the received roll-off bits state '11' for selecting a 15% roll-off filter.
In this case, it is favorable to choose the setting "reserved".In all other cases, it is recommended to
use the setting "standard" as this will guarantee compatibility with DVB-S2 receiving equipment.
