Note: DAC had 4x problem for these runs

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 behavior
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):
