Use this dialog box to configure user-defined properties for your .tdm or .tdms data.

This dialog box includes the following components:

Option Description
TDM Properties Use the TDM Properties tab to create user-defined properties for .tdm and .tdms files. Click the Insert button to add a new property to configure. Click the Delete button to remove the selected property.
  • Source—Use the Source column to specify the input source of the property information. The Source column contains the following options:
    • Ignore—Select this option if you do not want to write any of the property information on the specified row to the file.
    • Value—Select this option if you want to specify the property information in this dialog box.
  • Name—Use the Name column to specify the property name. The property name cannot contain any spaces or special characters. LabVIEW automatically replaces spaces and special characters with an underscore.

    • Channel—Select this option to append or overwrite the property value to the last channel in the file.
  • Insert—Inserts a new item above the selected item.
  • Delete—Deletes the selected item from the list.
DAQmx Properties Use the DAQmx Properties tab to select and edit DAQmx property names for .tdm and .tdms files. If you select any DAQmx properties that are unused in the specified file, LabVIEW does not write the properties to the .tdm or .tdms file.
