Rigol MEM-DS2000 Deep Memory Option

Increases the maximum memory depth to 56Mpts on DS2000A series digital oscilloscopes and MSO2000A series mixed signal oscilloscopes.

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. DS2000 provides up to 56 Mpts memory depth (option) and 14 Mpts standard 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)
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, 14kPoints, 140kPoints, 1.4MPoints, 14MPoints and 56MPoints. In “Auto” mode, the oscilloscope selects the memory depth automatically according to the current sample rate.

When CH1 and CH2 are enabled, the memory depths available include Auto, 7kPoints, 70kPoints, 700kPoints, 7MPoints and 28MPoints. In “Auto” mode, the oscilloscope selects the memory depth automatically according to the current sample rate.
