Calibrations
Expected value for most important registers in DAC Counts
CAL LAC : 15-20
CAL FLE : 15-20
CAL FHE : 15-20
CAL ULD : 15-20
CAL FHE : 15-20
TKR DAC : 15-20
Timing
The values shown below are based on the LAT Alignment and we will use these as default for CU tests. Note that this is for the flight configuration B2 that became LAT701 config. TEM diagnostics are not enabled and they will change these values.
Below is a timing diagram that explains how knobs are set to ensure charge is collected at the peak for all 3 detectors. Note that CAL beling the slowest its TREQ Delay is set to 0, while ACD being the fastest detector has more delays added.
Finally there are some plots from trigger jitter from Martin Kocian!LAT trigger jitter.gif!
