Investigation of the nature of the secon peak in the second hit mode.

1. LED is in non-updating mode, 30 mV threshold, 40 ns pulse width:

2. LED is in updating mode (in hope to get rid of the second pulse), 30 mV threshold, 40 ns pulse width:

Second pulse is still there.

Another case of the second pulse appearance (same conditions):
