The Dual Polarization Spectrograph, or DPS, produces SPS files.  These files contain the raw frequency sweep data.

CDF files for the DPS instrument are available from 2013 10 01 through 2022 08 31.  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/
