Measurements of ASIC V2. M.Borri STFC Measurements in h-mode.

Overview. Test01 ◮ GOAL: Test uniformity of channel response when pulses are injected. ◮ MEASUREMENT: Loops over all the channels. Only one channel is powered up at each time, and pulses are injected only on this channel. Test02 ◮ GOAL: Test linearity of channel over a range of test-charges. ◮ MEASUREMENT: Loops over all the channels. Only one channel is powered up at each time. For this channel, loop over several pulse-amplitudes. For each pulse-amplitude, inject N pulses. Test03 ◮ GOAL: Test peak-time agreement with its nominal value. ◮ MEASUREMENT: Loops over all the channels. Only one channel is powered up at each time. For this channel, loop over several pulse-widths, fixed pulse-amplitude. For each pulse-width, inject N pulses. Test04 ◮ GOAL: Perform indirect measurement of the energy threshold. ◮ MEASUREMENT: Loops over all the channels. Only one channel is powered up at each time. For this channel, loop over the energy threshold. Inject N pulse for each energy threshold. ◮ Repeat for several pulse amplitudes.
