<H2>Oscillator Short Term Stability and Aging</H2>
This is a table showing the stability specifications of as many
high-quality oscillators as I can get data for. All the numbers are
published specs unless a footnote says otherwise.

<H2>Phase Noise</H2>
And this is a table of phase noise specifications for synthesizers and
oscillators. Again, unless otherwise noted all are published specs.
In many cases, values are taken from published charts so there may be a
bit of guesswork about the precise values.
