Appending DAQ input to csv

[Rgibbs]

Hi, I am trying to append DAQ input to a csv file continuously. The DAQ is sampling at 41k and each loop is set to read 100k samples. Currently I have a waveform chart inside the loop which updates approximately every 2.5 seconds (100k/2.5k), I am unsure why placing a Write Delimited Spreadsheet (as shown in attached) inside the loop does result in data being appended to the file every ~2.5 seconds.

Thanks!

I don't understand your sentence there.

The problem I do see with your VI is that you have nothing wired to the file path input.  An empty input results in a file dialog as a default, which means every iteration, you will need to pick a file from the dialog.
