Object

scalar r/w Enumeration 
The transmit filter Roll-off factor setting determines the output spectrum
excess bandwidth by controlling the RCRO (Root Cosine Roll-off) factor of the
matched filter at the modulator output. The lower the Roll-off factor the
higher the throughput. Note that increasing the throughput (higher symbolrate)
requires more power from the satellite or will result in a lower
carrier-to-noise. All Roll-off factor settings can also be applied for DVB-S.
