FSW Requirement 5.3.12.5.3.1 (prev, next)

Req. 5.3.12.5.3.1: "CAL Charge Injection Histogram"

The FSW shall histogram the triggered event data, applying a commanded prescaling factor, forming a multi-peaked distribution. Note: The number of triggers at each amplitude is programmable, so that the number of events in each charge peak in the histogrammed data can be matched with the known input pattern of charge amplitudes.
