Short-Term Stability:
See Statistics of Atomic Frequency Standards by
David W. Allen, Proceedings of IEEE, Feb. 1966,
p. 221, and HP Application Note 116 for measure-
ment details.
Settablllty:
The degree to which an oscillator may be adjusted
to correspond with a reference. This is also
termed calibration.

1 MHz, 100kHz.
Harmonic Distortion: (5 MHz, 1 MHz, 100kHz)
Down more than 40 dB from rated output
Nonharmonically Related Output: (5 MHz, 1 MHz,
100kHz) Down more than 80dB from rated output
Signal-to-Noise Rallo: For 1 and 5 MHz,>87 dB
at rated output (in a 30kHz noise bw).
