Analog Testboard E1493


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):

Pedestal Plots

  Low Gain High Gain

Pulse Plots

Plot Description LAUROC1 Low Gain LAUROC1 High Gain
Overlayed pulses, to compare shape across amplitudes (HG cut off at 2048 due to saturation) pulse_overlay_lg.png pulse_overlay_hg.png
Linearity (Pulse height [ADC counts] vs. DAC value) low_gain_with_fit.png high_gain_with_fit.png
Nonlinearity of pulse height to DAC (differential) Nonlinearity_percent_differential_low_gain.png Nonlinearity_percent_differential_high_gain.png
Nonlinearity of pulse height to DAC (integral) Nonlinearity_percent_integral_low_gain.png Nonlinearity_percent_integral_high_gain.png

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

OFC Plots

Plot Description LAUROC1 Low Gain LAUROC1 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 of OFCs that sample just after peak    
Timing Resolution using out of phase OFCs
