The high resolution and low measurement uncertainty goals for next generation atmospheric sounders will require FTSbased spectrometers which exhibit improved velocity stability and disturbance rejection over previous systems. This paper documents the characterization of and improvements made to existing SDL FTS systems as part of an internal study to meet the demands of future missions. Improved velocity tracking and disturbance rejection performance is documented along with selected lessons learned.
