P2 PLL Measurements

jmg

I've spotted some nice PLL measurements in another forum, that it would be nice to apply to P2.

Someone may have the high end Allan Variance clock instruments, to get these plots on P2 ?

The new P2-Edge with the Clipped Sine TCXO should have the best reference clock stability
(these curves go out to ~60 seconds of average time)

Addit: Added TCXO examples, as max points on graphs

IQXT-205-1-33  (±0.50ppm)  : < ±1ppb,0.1s
TG5032CGN      (±280 ppb)  : < ±0.2ppb,1s

Not me, for sure, but the specs of the two top-liners are outstanding (as their prices can be).
