In the caption of Fig. 2 in this paper, there's the phrase 'fixed ramp', which I don't know the meaning and couldn't find any relevant explanation in quantum computing literature. There's description in the corresponding paragraph but didn't explain what they exactly did by 'ramping'. I guess it's something in electronic engineering but I couldn't find valid keywords to search for.

A ramp up (or down) is just a gradual increase (cq. decrease) of a signal. By 'fixed' I think they just mean at a fixed rate, i.e. linear.
