Output oscilloscope data to a CSV file

[JamesEvans]

I'm working with the VI from a Hantek DSO-2150 USB oscilloscope. LabVIEW shows the data in a graph but I'd like to output the results to a CSV file. I think the "Write to measurement file" control would be of use but I'm not sure how to use it. Would someone please help a newbie?

Thanks!

I did not see File I/O happen anywhere. Have you given it a shot at all? For your case, I would recommend using the Write to Spreadsheet File node.

Also, have a look at Fundamentals -> File Input and Output in the Example Finder (Help -> Find Examples) to look at some examples.

And, I would recommend that you change your architecture. Using Flat Sequence Structures is not the right way to program an application in LabVIEW. I would recommend you have a look at the State Machine Design Pattern (File -> New..) and consider that architecture so it can help you avoid issues in the future as your application grows larger.

Thank you for the advice! I've modifed it as attached below with a write to measurement file. It seems to be working! Could you suggest any improvements?

[AdnanZ]

That looks good, only consider using the state machine architecture like I mentioned above.

Thanks Adnan, the state machine sounds like an excellent idea. I am working with an oscilloscope and their software is somewhat lacking. One problem now is it takes 30,000 samples, writes it to file, and then takes 30,000 again. Could this be a limitation of the scope? I'd like to have "seamless data logging".

Thanks again for all of your help!

[AdnanZ]

Not sure; you'd have to look at the documentation.

[JamesEvans]

Ok thanks, once again I really appreciate your help!

And just to answer your original question:
The 'write to spreadsheet file' has an input for 'delimeter'.

By default, the delimiter is 'tab' but you can wire a ',' and it will use a comma as a delimeter.

Then if you save the file as *.csv excel should be able to open it no problem.
