+The full waveform digitiser (FWD) is supplied as an upgrade to the existing ALS50v2 (and up) sensors, and essentially consists of an upgraded data logger and an intensity digitiser (the FWD).  The discrete point recording subsystem is unchanged.  In implementation, the FWD is added as a spur after the automatic gain controller (AGC).  There is a trigger from the discrete system to the FWD that tells the FWD when to start recording.
