How to automatically extract the range of frequency and how to find the time for maximum values

Hi,

1. How can I search for each frequency range?
For example I looked into the excel file and I saw that 1kHz begin from line 61536 and is ended at line 62560:

.
.
.

Therefore I extracted manually the respective range in Mathcad:

So, for example I want to know between what range the 0.001Hz begging and ends, but without staying and looking into excel file, some automatic routine if can be made in Mathcad:

And then I want to know the maximum value for Vout and Vin at the respective Frequency and at which time these maximum values are occuring:

Above its only the maximum value at 1kHz, but I do not know at what time these maximum values for Vout and Vin are occuring.

Because I want to know then the difference between t2-t1.
