DAC Plots

Test Point V vs. DAC: Linearity
- Left, full range; right, zoomed at low values (to show DAC turn on)
- Fit boundary points are chosen by hand to indicate bounds of linear behavio

TODO

Test Point V vs. DAC: Nonlinearity
- Left, differential (percentage of current pulse height); right, integral (percentage of max pulse height)
- Fit boundary points are consistent with linearity plots above

TODO

- With restricted y-axis (to show nonlinearity only over linear operating range):
