I can manually override the ramp and set a voltage which will show up a glitch in the frequency domain, which is a useful plus. You reckon it would be better to use a DSO for this? I do have one. Frequency domain glitch? You mean a discrete spur? A glitch is a transient time-domain animal. A DSO can save a single instance, or (with averaging) ignore the noise and asynchronous background and just reproduce the glitch itself.
