Analog Testboard E149373

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
COLUTA1/ADC1
COLUTA2/ADC2
DRE 4x Mode	Low Gain	High Gain
COLUTA1/ADC1
COLUTA2/ADC2

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)
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)

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
