It provides "delay by events", producing a trigger output pulse after a selectable number (0 − 99,999) of input trigger events. | |||
== | {{BeginSpecs}} | ||
{{Spec|Event count|0 to 99,999 }} | |||
{{Spec|Max. count rate|80 MHz}} | |||
{{Spec|Insertion delay|≤ 30 ns}} | |||
{{Spec|Recycle time|≤ 25 ns}} | |||
