Strobe delay analysis for Stars
Implementation and analysis for strobe delay scan.
StarStrobeDelayFitter
is a AnalysisAlgorithm
which takes in occupancy maps and does the following:
- for each channel, make a histogram of occupancy vs strobe delay
- fit the rising and falling edge of the histogram from 1 using two s-curves
- find the max rising edge and min falling edge among all channels within a chip
- define the optimal strobe delay setting to be 57% between max rising and min falling
Results are dumped into JsonData
files as well as in the following plots:
- occupancy vs strobe delay for individual channels (if option dumpDebugSDPlots is true)
- distributions of rising and falling edge for all channels
- 2D histograms of occupancy vs strobe delay vs channel number, separated by chip and by row
The config std_strobeDelayScan_fileInputs_template.json
can be used to run the analysis on occupancy maps from a previous scan.
