Oscilloscope tests the waveform, that is, it is connected to the ground of the equipment through the grounding clip, and the probe contacts the measured signal. What kind of signal waveform is beyond the control of oscilloscope. Oscilloscope is only responsible for showing its appearance truthfully.
The signal generator can output waveforms, and any waveforms you say can be output. JDS30 12A of Kim Electronics has the function of oscilloscope+signal generator, so we can pay attention to it.
