White Rabbit Switch noise measurement

I measured the CLK2 10 MHz RF-output of two White Rabbit switches with a Microsemi 3120A. The results are similar to previous results with ADEV(1s)=1.5e-11.

When phase-locked to an external reference clock the long-term stability is obviously much better than when free-running, but for small tau, or high offset-frequency in the phase noise plot, the free running oscillator is actually better.
