The Roll-off menu is used for setting the receiver’s roll-off factor value according<br />

to the roll-off factor of the transmitted signal.<br />

The Roll-off factor is the factor that is used for the base-band shaping of the<br />

transmitted signal. Set the Roll-Off factor in accordance with the transmitted<br />

Roll-Off factor. The following figure illustrates the Roll-Off screen.<br />
