Procedure[edit | edit source]

The curve used for the noise estimation

In order to estimate the noise, a test pulse is injected on each channel of the ASIC and a threshold scan is performed in the meanwhile. To measure the noise, we can fit the curve pointed by the blue arrow in the figure. The fit is performed with an error curve and the sigma of this fit gives the noise estimation.
