Calibration: CAL Integral Non-linearity
ID: C20 in LAT-MD-00446-04
Description: This is the look-up table which results from charge injection calibration and provides the conversion from possibly non-linear ADC scale to the linear DAC scale.
Software required: EGSE
Algorithm: The calibration input pulse height is defined in terms of DAC settings. For each DAC setting one provides 1000 charge injection pulses and obtain the average ADC value of the peak of the distribution. The conversion is accomplished by using a look-up table where adjacent points are linearly interpolated. To be expanded by CAL.
