A Digital Storage Oscilloscope (DSO) acquires signals with digital sampling using an analog-to-digital converter (ADC). A DSO scope uses a serial-processing architecture to control acquisition, user interface, and the raster display.

It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides.

Traces can be stored indefinitely or written out to some external data storage device and reloaded. This allows, for example, comparison of an acquired trace from a system under test with a standard trace acquired from a known system. Many models can display the waveform prior to the trigger signal.

The displayed trace can be manipulated after acquisition; a portion of the display can be magnified to make fine detail more visible, or a long trace can be examined in a single display to identify areas of interest. Many instruments allow a stored trace to be annotated by the user.
