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. The oscilloscope provides up to 28 Mpts memory depth.
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. Aavailable memory depths include: 28k, 280k, 2.8M, 28M.
Since the oscilloscope has two acquisition memories, when only one channel is on,
the maximal memory depth is up to 28 Mpts.
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 2 GSa/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
pan and zoom the waveform.
