Memory Depth

Memory depth refers to the number of points of the oscilloscope that can store in one
trigger acquisition. It reflects the storage capability of the acquisition storage. This
oscilloscope is equipped with a standard memory depth of up to 500 Mpts.
The following equation shows the relations among memory depth, sample rate, and
horizontal time base scale:
——indicates the memory depth. The unit is pts.
MDepth
——indicates the sample rate. The unit is Sa/s.
SRate
——indicates the horizontal time base scale. The unit is s/div.
TScale
——indicates the number of grids in the horizontal direction. The unit is div.
HDivs
Therefore, under the same horizontal time base scale, a higher memory depth can
ensure a higher sample rate.
In the Acquisition menu, click Mem Depth to select the desired memory depth. By
default, the memory depth is 1M.
