+It seems that the digital filter does not pass this test if the pulse form changes for more than 2\,ns from the 
 expected one. The effect is not as problematic as it may appear here, because the actual calibration 
 will not calculate the number of photo-electrons (with the F-Factor method) for every signal intensity.
