Memory Depth
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. DS6000 provides a memory depth up to 140 M points.

Memory Depth
The relationship of memory depth, sample rate and waveform length fulfills the
following equation:
Memory depth = sample rate (Sa/s) × waveform length (s/div × div)
Press ACQ  Mem Depth, use to select the desired memory depth (the default
is auto) and then press the knob to select the option. You can also press Mem
Depth continuously to switch the memory depth.
When single channel is turned on, the memory depths available include Auto,
14kPoints, 140kPoints, 1.4MPoints, 14MPoints and 140MPoints. In “Auto” mode, the
oscilloscope selects the memory depth automatically according to the current sample
rate.
When double channels are turned on (CH1 and CH2 or CH3 and CH4), the memory
depths available include Auto, 7kPoints, 70kPoints, 700kPoints, 7MPoints and
70MPoints. In “Auto” mode, the oscilloscope selects the memory depth automatically
according to the current sample rate.
