Abstract:
An event detector system, comprising:a first detector comprising a plurality of zones, each zone including a plurality of detector devices, wherein each zone generates a zone trigger signal when an event is detected by a detector device in the zone;a first energy source coupled to the first detector, such that when the first energy source is active, events occur that are detectable by the first detector; anda calibration circuit coupled to the first detector, wherein the calibration circuit performs timing calibration of zone trigger signals of zones of the first detector with respect to timing of a reference zone trigger signal of a predetermined reference zone of the first detector, and wherein the zone trigger signals and the reference zone trigger signal are generated when an event is detected,wherein the calibration circuit comprises a trigger calibration register, wherein a clock input of the trigger calibration register is coupled to the reference zone trigger signal and data inputs of the trigger calibration register are coupled to the zone trigger signals.
