Measuring with 500 kHz and Data Acquisition with Labview
I am using Labview to acquire Data from my Dewetron. So i have to measure with 500 kHz because of instationary pressure sensors. My hardware supports measuring until 500kHz. Actually i am using the method GetDataValues1 (IChannelConnection). When i am measuring 1 second, i should have 500.000 points, but i have only 3 or 5 points. I think the method GetDataValues1 (IChannelConnection) does not read from the direct buffer. Which method should i use to measure such high frequencies and reading the direct buffer? I found something like DBValues and DBValuesDouble.
Thank you for your help!
can I ask if this question is about plugin or DCOM automatization?
I use the dewesoft as an activeX in my labview Code, so i think it is dcom.
thank you for the Matlab Code. I have to work with LabVIEW and have some more questions.
How can I implement the Plugin (IPlugin) into my LabVIEW code, do I have to download the plugin? Actually I work with the IApp function. For help, I use Dewesoft v. 6.6.8 . The problem is, that I use an existing LabVIEW code that works fine and I have to add this function. Can you explain how to add the OnGetData functionality to my LabVIEW code and whether I have to add something to my Dewesoft or LabVIEW library.
Thank you very much.
