Page 85: Set The Record Length
CONFIGURATION Set the Record Length Background The number of samples that can be stored is set by the record length. Record length is important in an oscilloscope as it allows longer waveforms to be recorded. The maximum record length for the GDS-2000E depends on operating mode.
Page 86: Segmented Memory Acquisition Overview
GDS-2000E Series User Manual 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.
Page 87 CONFIGURATION 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.
