How to use RIGOL digital oscilloscope to observe waveforms over a period of time?

The oscilloscope cannot continuously capture and save waveforms. If it is in automatic mode, the oscilloscope will refresh the waveform data continuously.

If you need to capture the continuous waveform of the signal within a period of time,

you can follow the steps below to set it:
1. Set the storage depth to the highest.
2. Adjust the time base to the appropriate gear and set it according to the time you want to observe. For example, if you want to observe 1S of time, then set the time base to 100ms/Div. At this time, the time on the entire screen is 100ms*14 grids (DS2000) = 1.4s.
3. Select the trigger mode as single trigger. When the waveform meets the trigger condition, the waveform is captured and stably displayed on the screen.
