Our lab acquired two of these ultra-low phase-noise Morion MV272 OCXOs mainly for checking phase noise on distribution amplifiers.
The wavy fill is the estimated noise floor of the phase-noise test set.
Below are the data sheet specifications and the actual phase noise measured over a 10-hour averaging period. It performs far better than expected. My next big task will be to design a buffer amplifier that will not degrade the phase noise performance of the oscillator!

That's pretty good. I'm assuming that the oscillator power is 15-20 dBm? If so, then the performance is approaching the theoretical limit of -174dBm for a room temperature device. Since the oscillator is ovenized, this performance is also amazing.
If your oscillator is less than 10dBm output, you might want to check your calibration.
These units were not cheap and with a few months waiting time ordering from Morion.
But still BVA OCXO 8607 is one order of magnitude better than this Morion quartz (in terms of ADEV at tau=1s) Unfortunately it went out of production some time ago.
