The use of adaptive precorrection is generally preferred not only in order to reach
higher performance and efficiency, but also in order to save on technician time.
However, when several RF signals are combined together (adjacent channels), the use
of Linear DAP is not possible because the feedback signal is then a combined spectrum
of several channels. In that case a manual Linear precorrection is needed.
