◮

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

  • nly 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

  • ver 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

  • ver 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

  • ver the energy threshold. Inject N pulse for each energy threshold.

◮

Repeat for several pulse amplitudes.
