As described above, clicking “Acquire” will save spectra to disk; but where will it save it, in what format and with what fields? You can configure those options in the Scope Setup screen, which offers a variety of standard spectral management formats and options.
220.127.116.11 Saved File Formats
Spectra can be saved in either Comma-Separated Value (.csv) or Excel (.xls) formats. Microsoft Excel can open .csv files as well; the main difference is that CSV are more useful for dynamic programming and scripting, while the .xls files include some automated formatting and worksheet breakouts.
CSV files offer additional options over XLS files: they can be saved in either row-order or column-order format, meaning spectra can extend horizontally in rows (one line per spectrum) or vertically in columns (one line per pixel).
In addition, CSV files offer a special “append” mode, in which each new spectrum saved is automatically appended to a single CSV file. This is a convenient means to create strip-charts of temperature and other attributes, for instance.
18.104.22.168 Saved File Fields
Besides specifying the format of the file, you can also exercise choice in what fields get written to CSV files. Although “wavelength” is saved by default, you can also choose to include the pixel index, wavenumber (for Raman spectrometers), the last-saved “dark” spectrum, the latest “reference” (absorbance/transmission modes only), and a “raw” spectrum.
The “raw” spectrum contains no absorbance or reflectance/transmission post-processing, and does not include boxcar smoothing. However, it does include multiple scan averaging and bad pixel correction.
Future versions of ENLIGHTEN™ will support the “Optional Fields” checkboxes in XLS files as well.

You can also specify an alternate directory to save your data, if the default (“My Documents\EnlightenSpectra”) does not suffice.
