peak intensity vs number of scans
 

Hi,
I have a question regarding how the peak intensities change when with increase in number of scans when the data is collected on a Varian NMR spectrometer. Suppose I collect a 15N-1H HSQC spectra with 8 scans and then collect the same spectra with 16 scans, would the peak intensities be double in the 16 scan spectra as compared to the 8 scan spectra? Does anyone know how the varian spectrometer scales the intensities according to the number of scans? Any suggestion or reply to my query will be extremely useful and greatly appreciated.

Thanks.
