Issue Details

I am using the TDMS write to log waveform data to a TDMS file. I am viewing this file using the Excel Importer tool I got from National Instruments. However, I am only getting one sample of data in the file. I can probe my wires to confirm more data is being written, but the file only shows one sample per channel. How can I fix this?

Solution

The Excel Importer tool is not able to look at TDMS files as they are being written to. To view all of your data:
  1. Close Excel
  2. Run your acquisition program
  3. Close your acquisition program
  4. Open your TDMS file with the Excel Importer

Additional Information

If you would like to view your TDMS files as they are being written to, you can use the TDMS File Viewer VI  and pass that VI the TDMS file name.
