WebRoll-off factor: Supported roll-off factors are 0.2, 0.25, and 0.35 Symbol rate calculated as B / ( 1 + R ), where B is the channel bandwidth, and R is the transmit filter roll-off factor Pilot symbols: Optionally added at the transmitter for carrier recovery at the receiver RF Impairments in a Typical DVB-S2 Signal WebThe shape factor is the ratio of bandwidths measured using two different attenuation values to determine the cutoff frequency, e.g., a shape factor of 2:1 at 30/3 dB means the bandwidth measured between frequencies at 30 dB attenuation is twice that measured between frequencies at 3 dB attenuation.
