Page 111: Segmented Memory Acquisition Overview
CONFIGURATION Segmented Memory Acquisition Overview 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 112 GDS-2000A Series User Manual Segmented memory acquisition example: Segment Segment Segment Segment Segment Segment As shown below, 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.
Page 113: Segments Display
CONFIGURATION Segments Display Run/Stop Indicator Progress Indicator Indicates the number of Progress Indicator segments that have to been captured relative to the set number of segments. Stop: The segments have finished Run/Stop Indicator acquiring or have been stopped. Run: The scope is ready to acquire segments.
