File Info - Generator Setup Title

Controls: File Menu >> File Info >> Setup Title

If the file currently open (or the most recently-loaded Arb or Play file) is a .DQA file, and if that file was created using the Daqarta Generator, then the title of that Generator Setup is shown here. This might be especially useful if you want to replicate a prior experiment that produced the data file, or to create a similar Arb or Play file.

This will show 'Generator not used' if no output channels were active when the .DQA file was created.

The Generator Setup title is not applicable to .WAV and .DAT file formats, since they do not contain information about Generator use, so this item will show '(N/A)'.

These two file formats also don't contain Notes text or User Units calibration information. However, for long (more that 1024 samples) .WAV files only, you can add that information after opening the file. When you close it, you will be prompted to save the changed file. If you accept, it will be saved under the original file name, including the .WAV extension, but it will really be a .DQA file. When you subsequently open the file, this item will show 'Generator not used' as noted above for .DQA files.

To tell a modified .WAV from a standard .WAV, check the Generator Setup Title in the File Info dialog. A standard .WAV will show '(N/A)' while a modified .WAV will show 'Generator not used' since it is really a .DQA file.
