All of the different file write functions (Write LabVIEW Measurement File, Export Waveforms to Spreadsheet File, Write to Spreadsheet File) write 'tables'. The differences are in the header and column information. The reason I suggested Write LabVIEW Measurement File is that you can wire the dynamic signal data from the DAQ Assistant (still use only one) directly without having to do a conversion. How are you configuring the DAQ Assistant (i.e. number of samples), how often do you want to save? What else do you want in the file besides the measurements?
If you can post what you've written so far, it would help to see where you are having having problems. Just saying you have a problem doesn't help if you don't explain exactly what the problem is.
