Recording data for power spectral density

[bns2804]

Hello

I need to record the power spectrum for a duration of 2 weeks for 2 hours per day. I can get the averaged power spectrum for the 2 hour duration per day as it is embedded in the Power Spectrum Function. Is there a possiblity of saving the data to some Excel file and later calculating the averaged power spectrum for the whole 2-week duration..

Please Help. Thank you.

I was save the data into a TDMS file.  The API is fairly simple and there is a free add on to view the data in Excel.

You can later also read the TDMS file and do whatever averaging, etc you want to do with the data.
