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 sample
memory. DS1000Z provides up to 24 Mpts memory depth (option) and 12 Mpts
standard memory depth.

Memory Depth
The relation of memory depth, sample rate and waveform length fulfills the equation
below:
Memory depth = sample rate (Sa/s) × waveform length (s/div × div)
Thus, in the same time base, the higher memory depth can ensure a higher sample
rate.
Press Acquire Mem Depth, use
to switch to the desired memory depth (the
default is auto) and then press down the knob to select the option. You can also
press Mem Depth continuously to switch the memory depth.
When a single channel is enabled, the memory depths available include Auto,
12kPoints, 120kPoints, 1200kPoints, 12MPoints. In “Auto” mode, the oscilloscope
selects the memory depth automatically according to the current sample rate.
When two channels are enabled, the memory depths available include Auto, 6kPoints,
60kPoints, 600kPoints, 6MPoints. In “Auto” mode, the oscilloscope selects the
memory depth automatically according to the current sample rate.
