All acquisition modules like Scan, Spectroscopy, ... now have access to the full signal list (instead of a pre-selected list of 24 signals). The Signals Assignment is no longer needed and has been removed.
Be careful when using the programming interface to set the acquired channels in these modules, since the signal indices have a different meaning now (they are now indices of the full signals list, see Signals Manager for the indices).
