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

  • 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):

Pulse Plots

Plot Description LAUROC1 Low Gain LAUROC1 High Gain LAUROC2 Low Gain LAUROC2 High Gain
Overlayed pulses, to compare shape across amplitudes (HG cut off at 2048 due to saturation)        
Linearity (Pulse height [ADC counts] vs. DAC value)        
Nonlinearity of pulse height to DAC (differential)        
Nonlinearity of pulse height to DAC (integral)        

  • Gain Plots (deriving gain ratio & comparing LG to HG)
COLUTA1

COLUTA2

OFC Plots

Plot Description LAUROC1 Low Gain LAUROC1 High Gain LAUROC2 Low Gain LAUROC2 High Gain
Energy Resolution of large, unsaturated pulse        
E from OFCs (in ADC counts) vs Pulse Height (in ADC counts)        
Timing Resolution of OFCs that sample at peak        
Timing Resolution using out of phase OFCs
