Paul, everything I seen

Always on till a brief pulse from the 1 or 2 MHz ref cuts it off. I

if you have enough buffering -- look for now noise amplifiers, which
have low h12 [= backward gain ] a quartz oscillator will not lock so
easy

HI
As long as you have a really poor crystal oscillator (wide band loop) they are
quite easy to lock. If you have a high performance crystal oscillator (high Q /
narrow band loop) they are relatively difficult to lock. If you are trying to
*guarantee* a lock bandwidth and *guarantee* a level
Dear Francesco,
Connect the two oscillators to a mixer, which will provide a path into
the clock under test and provide a beat note for monitoring. Adjust the
EFC and observe the locking width, when the beat note is missing.
Cheers,
Magnus

Any comment about close-in phase noise performance when adding
injection locking to such oscillators?
