SDS1000X-E&SDS1000X-U User Manual

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.
Press the Acquire button on the front panel; press the Mem Depth softkey and then
turn the Universal Knob to select the desired value and push down the knob to
confirm. Press the Mem Depth softkey continually can also select the desired value.
The actual memory depth is displayed in the information area at the upper- right
corner of the screen. Since the oscilloscope of SDS1000X-E has two acquisition
memories, when only one channel is on, the maximal memory depth is up to 14
Mpts. SDS1000X-U only has one acquisition memory, when only one channel is on,
the maximal memory depth is up to 14 Mpts.
The maximum storage depth in single channel mode is twice that in dual channel
mode, as shown in the following table:

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)

Sampling Mode

The oscilloscope only supports real-time sample. In this mode, the oscilloscope
samples and displays waveform within a trigger event. The maximum real-time
sample rate is 1GSa/s.
Press the RUN/STOP button to stop the sample, the oscilloscope will hold the last
display. At this point, you can still use the vertical control and horizontal control to
