Select 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 14 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. Memory depth that available: 14K, 140K, 1.4M, 14M.
Since the oscilloscope has two acquisition memories, when only one channel is on, the
maximal memory depth is up to 14 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)
Select 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 pan and zoom
the waveform.
