    5.2 AIM+: Using the spectrum analyser to detect and mitigate interference The PolaRx5S is equipped with a sophisticated RF interference monitoring and mitigation system (AIM+). To mitigate the effects of narrow-band interference, 3 notch lters can be con gured either in auto or manual mode. These notch lters effectively remove a narrow part of the RF spectrum around the interfering signal.
