+    * Meme probleme
+On prend commme piedestal **737970**
+  * Tous les canaux allumes + cable d'injection (737974)
+    * mean ~ 474
+    * RMS ~ 2.5 cx bruyants 3.3
+Threshold= 474+5*3.3 ~ 491
+On essaie on doit mettre **496**
+Si on regarde la calibration cela nous donne
+**VTH (mV)= (496-474)/0.1743 = 126 mV**
+mais la calibration n'est pas sur un canal mais sur les 2 cotes
+donc **seuil minimal ~ 63 mV ou fC**
+Pas si eloigne que ca des 50 fC prevus
