Perform division

If checked, the active measurement is divided complex with the reference measurement. If the sampling frequency is not the same for the active and the reference measurement, no division is performed and an error message is displayed.

The zero-padding size has to be the same for the two measurements or else the division will not work, also the zero-padding size must be larger than the window size for both measurements to prevent truncation. Therefore the longest Time Data Window of the two measurements is used as basis of finding the zero-pad size.
