How do I output digital/analogue signals based on a text file

I have a CSV file with three fields in each record; time, rpm, and a voltage. A sample file is attached. The rpm numbers are generated using 8 counts/revolution. I want to replicate this file somehow. At a trade show this past weekend I was told Labview could possibly read this file and output the signals. How would this work? I develop an app in Labview that reads the txt file and then run the app. The app generates the signals using what device? Any info is greatly appreciated, thanks in advance

Many of the National Instruments hardware cards (or potentially third party manufacturers) can be used by LabVIEW to create analogue and digital I/O signals from a text file.

The PCI cards often have 2 analogue outputs and 8 analogue input channels (often more), as well as Digital I/O's and counter timers.

I suggest that you firm up your requirements and contact your local NI sales office for specific hardware advice.

Hi Toby,

If you are looking at generating both analog and digital signals, a good option for you may be one of our Multifunction Data Acquisition boards.  More information about the various products we have in this line can be found here.
