Stability and Phase Noise Specifications
Oscillator Short Term Stability and Aging
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.

1Aging specs are subject to various qualifiers. The value here
is the best per-day figure cited by the manufacturer.
2Here is an HP document listing
HP10811 variants and specifications. Published with Agilent's
permission.
3Used in Z3801A GPSDO.
4Measured
performance of N8UR's Sulzer 2.5 standard.
5The 100 second specification is actually for 120 seconds.
6Specs for option 015 (disciplined oscillator).
Phase Noise
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.
