Noise and Drift

Hello
 I have a question about noise and drift for  my tests, I need noise and drift to be calculated for each step of the image. How can I calculate the noise and drift separately for each time interval of the start of the step and the end of the step? (OpenLAB CDS 2.4)
The following sample output that is needed in Excel is as follows, which is filled manually for each step.
