[time-nuts] Better than Quartz?

[Murray Greenman]

Peter,

That's is essentially the point - it is the Q of the resonator (assuming
environmental effects are controlled) which ultimately determines the
stability. Very high performance oscillators (the HP E1938A is an
example) use a bridge circuit to enhance the loaded Q of the crystal.
Other designs (the QAS and BVA) use a complex structure of crystal which
places the electrodes outside the oscillating structure in order to
enhance the loaded Q.
