8.4.7.1 Linear Pre-correction on DVB-S/S2 Output.
In order to compensate both linear distortions in the transmission chain, it is possible to adjust the modulator
output to match these characteristics. This is done via the pre-correction configuration page. When using the
linear pre-correction algorithm, both Gain and Group Delay correction is supported.
