15.Segmentation Acquisition
When triggering several times in the acquisition process of the segmented storage, the
data obtained from the sampling of each trigger is stored in the storage space of each
segment.
15.1.The principle of segmentation storage.
As shown in the figure below,the data acquired when the first trigger occurs is stored in
the first segment storage space, and the data acquired when the second trigger occurs is
stored in the second segment storage space. By the same analogy, the oscilloscope
enters the pause state to finish the acquisition process when the number of segments set
by the user is acquired. Read the first segment of the acquisition for display.
Take MPO6000EDU as an example,total storage depth is 128Mpts, The calculation
formula of segment number distribution is as follows:
N=128*1024*1024/
【
The current storage capacity integer to the Nth power of 2
】
-1
The maximum storage of MPO6000EDU is 128Mpts, Under the condition of maintaining
1GSa/s sampling rate, the segmented storage range is supported: 1~80000 segments.
