You just have to use the Index Array function. If you are getting a waveform data type, you'll have to use the Get Waveform Components function first to get the Y array. There are many file I/O functions. You can use the Write to Measurement File, Write to Spreadsheet File, or if you have the Report Generation Toolkit, you can use that. The search function will turn up thousands of posts on the subject. Try using it.
Pretty basic stuff. Take a look at the free LabVIEW tutorials.
p.s. The board you posted to is for a product called Measure. Nothing at all to do with your question.
