---++ 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):
