To Set the Memory Depth
The memory depth refers to the number of waveform points that the oscilloscope
can store in a single trigger sample and it reflects the storage ability of the
acquisition memory. DS4000E provides up to 14 Mpts memory depth for each
channel.

Memory Depth
The relation of the memory depth, sample rate and waveform length fulfills the
equation below:
Memory Depth = Sample Rate × Waveform Length
Wherein, Waveform Length = Horizontal Time Base × number of grids horizontally
on the screen. For DS4000E, the number of grids horizontally on the screen is always
14. Therefore, with the same horizontal time base, higher memory depth can ensure
higher sample rate.
Press Acquire  Mem Depth, turn the multi-function knob to select the
desired memory depth (the default is auto); then, press the knob. You can also press
Mem Depth continuously to switch the current memory depth.
 The memory depth can be set to Auto, 7 kPoints, 70 kPoints, 700 kPoints and 7
MPoints.
 In “Auto” mode, the oscilloscope selects the memory depth automatically
according to the current sample rate. As the sample rate might change when
adjusting the horizontal time base, the memory depth might also change
accordingly.
