FSW Requirement 5.3.12.5.3.3 (prev, next)

Req. 5.3.12.5.3.3: "CAL Charge Injection Calibration Mode Data Histograms"

To minimize confusion in the interpretation of the histograms, the FSW shall create several histograms, each covering a limited subset of charge-injection amplitudes, for a single CAL charge-injection calibration. The amplitudes chosen for each subset would span the full dynamic range of charge injection, but they would be interleaved from subset to subset.

Test(s)

    014: LAT Diagnostic and Calibration Modes

    This test shall verify that the SIU FSW properly transitions to Diagnostic and Calibration Modes upon command, then properly executes the requested diagnostic and calibration algorithms.
