The FS-200B spectrograph produces SPS files.  These files contain the raw frequency sweep data.

CDF files for the FS-200B instrument are available from 2014 01 01 through 2016 06 07.  The CDF files were generated from the original SPS files by Jim Sky using a custom file conversion routine.

CDF is a NASA standard: https://cdf.gsfc.nasa.gov/ 

SPS and CDF files may be plotted using Autoplot: http://autoplot.org/
