FSW Requirement 5.3.12.2.1 (prev, next)

Req. 5.3.12.2.1: "Threshold Scan Measurements"

For each channel, the FSW shall measure data capture efficiency for several threshold points at a fixed calibration DAC value. Note that every 32 channels can be pulsed at the same time (48 channels per layer).
