Typical TAPR Thunderbolt phase noise is about -100 dBc/Hz at 1 Hz, falling to about -150 at 100 Hz, with a floor just above -160 beyond 10 kHz. Variations on this, and spurs, seem to be a function mostly of power supply. For example, see: http://www.leapsecond.com/pages/tbolt/noise.htm
Given the apparent sensitivity to the power supply that the Tbolt exhibits, has anyone put any effort into optimizing the power supply so as to minimize that set of effects?
ie: what is the best power supply to use to ensure maximum accuracy for the Tbolt? A couple of linear supplies? Any particular switcher?
