using counter to time stamp to text file

[Georgeycw]

Dear all,

I am using counter to acquire singnal from quadrature linear encoder. I would like to time stamp the data acquisition to text file but I found that I can't choose to read time. Anyone know how to solve this problem?

Attachment is my program.

Thank you very much!

Best regards,

George

Hi,

Have you seen these two articles?

Basically, it can be done, but be aware it may not be as accurate as you would like.  Follow the code in the first article and note that the easiest way would be to just use the basic File I/O VIs to write to text file, since the Write to Measurement File VI will only work with waveforms and you have counter output.
