An oscilloscope includes at least one demonstration signal generator integrated as part of the oscilloscope. The demonstration signal generator generates stimulus signals that consist of digital samples of various different stored waveforms without the need of a separate demonstration board or signal source. The demonstration signal generator may loop through different sections of the stored waveforms to generate respective stimulus signals that include sequences of digital samples from the different waveforms in combination, to provide a broad range of stimulus signals. The stimulus signals may be displayed on the oscilloscope or output from the oscilloscope as demonstration mode stimulus signals to demonstrate the capabilities of the oscilloscope to customers or for training.

Oscilloscope with internally generated mixed signal oscilloscope demo mode stimulus, and integrated demonstration and training signals

In an exemplary embodiment of the present invention, a master oscilloscope propagates a slave signal to one or more slave oscilloscopes. The slave signal includes a synchronized trigger pulse that is used in the master oscilloscope to provide a display of a first signal and also includes a timing interpolation parameter which indicates a timing delay applied in the master oscilloscope with respect to the synchronized trigger pulse when providing the display. A slave oscilloscope can use the synchronized trigger pulse and the timing interpolation parameter to provide a display of a second signal on the slave oscilloscope, thereby ensuring that a triggered edge of the second signal is time-aligned with a triggered edge of the first signal. This arrangement reduces/eliminates absolute as well as relative timing uncertainties when an observer observes the first signal displayed on the master oscilloscope and/or the second signal displayed on the slave oscilloscope.
