[time-nuts] Vibrations

[Raj]

While comparing a Rb FE5680 frequency reference with another RB or GPSDO I find that tapping a Rb unit causes a sudden shift in the scope display meaning the frequency has slightly shifted momentarily and locks back steadily with a phase shift. This does not happen in another Rb FE5680.

Would something be loose I wonder ? Any experiences?

Cheers
