    ADVANCED CONFIGURATION Segmented Memory Acquisition The advanced segmented memory utility allows the scope memory to be divided into different segments. Each time the scope is triggered, it only acquires data for one segment of memory at a time. This allows you to optimize the scope memory to only perform signal acquisition during important signal events.
  • Page 88 MDO-2000EG & 2000EX User Manual Segmented memory acquisition example: Segment Segment Segment Segment Segment Segment As shown above, the memory is divided into segments to increase the number of events that can be effectively captured with the same acquisition memory. Also notice that the scope doesn’t need to rearm the trigger between each segment, this makes the segmented memory function especially useful for high speed signals.
