100 Things #28: Autosave SoundCheck Data to a Variety of Formats

The autosave step in SoundCheck is a powerful feature that allows you to save the curves, values, results and waveforms generated in your audio tests in the format and location of your choice while the sequence is running. Data formats include text, csv, Microsoft Excel, Microsoft Word, Matlab, WAV, TDMS, database as well as the native SoundCheck dat, results and waveform formats.

Video Script: Autosave SoundCheck Data to a Variety of Formats

The ability to automatically save data in a sequence has been a SC feature since it’s inception. No other audio test and measurement system offers the Autosave options and flexibility found in SoundCheck.  SoundCheck can save to a variety of formats including text, csv, Microsoft Excel, Microsoft Word, Matlab, WAV, database as well as the native SoundCheck dat, results and waveform formats.

The ability to save sequence data every time a sequence is run is a clear benefit for the production line test environment.  Curves, values, results and waveforms can be saved for each device under test, preserving the test data for future statistical analysis.

Autosave steps are generally found at the end of a sequence, after all of the data and results have been generated.  Step templates are available for the most common autosave formats.

Here’s the Save to Dat autosave step. At the top, I have the ability to select whether data, results or waveforms are to be auto saved and you can see that as I toggle through these options, the memory items in the list are filtered based upon my selection.  The data to be saved is determined by selecting the desired items in the list using standard click, shift+click, ctrl+click functions.

Once you’ve selected the items to be saved, you can assign the location to where they will be saved. By default, this will be your SC data folder but you can also save to any location on a local or network drive or portable media storage.

Below the folder path control, is the data formatting drop down. Depending on the selected format the various options may or not be available. You can see that as I switched from SC format to Excel that many of the options became active including the options to use an Excel template, Axis selection, Layout, Header configuration and Notation.

Test information is appended to the saved data’s name so If I select Time, the saved data selected above will be appended with a time stamp every time it is saved.

The final configuration is for how the file will be saved and file name construction.  This gives the user options to create overwrite or append data to an existing file when saving and whether this should be an automatic operation or prompt the operator with a file save dialog.  File name construction is done using a template format using default options such as sequence name, time. Serial number as well as a user defined field.

For this example, I’m going to use the default template construction using the sequence name and date.  [close the editor and run the sequence a few times, then open the Excel file to show how the data has been saved.

We can never have enough data no matter if we’re working in R&D or production and the autosave step is a powerful Soundcheck feature that allows you to save the data you want in the format you want and in the location you want.  Future versions of SC will include even more autosave formatting options so stay tuned and thanks for watching!
