I’d want to adjust the baseline based on what I saw on-screen. In this case, I would set it to ~16 ma level, the ‘baseline’ from which I want to calculate the additional current, i.e. the area above the baseline and between two vertical cursors. I suppose it could also be done with a click and drag to form a bounding rectangle.
I added a baseline and a bounding rectangle to indicate what I’m interested in. The Joulescope is an energy analyzer, but why limit the analysis to total energy over some time window? The energy contribution of a periodic event can also be of interest, especially if modifications can be made to alter that event’s energy profile. Now I suppose if the baseline was always the same rock solid value, you could still make comparisons using dual cursors only to see if you’ve made improvements, but that might not always be the case.
Food for thought, anyway
