—Phase noise and frequency stability both describe the fluctuation of stable periodic signals, from somewhat different standpoints. Frequency is unique compared to other domains of metrology, in that the fluctuations of interest span over at least 13 orders of magnitude, from 10 − 4 in a mechanical watch to 10 − 17 in atomic clocks; and over 12–15 orders of magnitude in the frequency span, or the time span where the fluctuations occur. Say, from µ Hz to GHz Fourier frequency for phase noise, and… 


Phase noise and amplitude noise in DDS
Their article reports on the measurement of phase noise and amplitude noise of direct digital synthesizers (DDS), ultimately intended for precision time and frequency applications. The DDS noise
Correlation-based phase noise measurements
In the characterization of the phase noise of a component, it is common practice to measure the cross-spectrum density at the output of two phase detectors that simultaneously compare the component
Characterization of phase and frequency instabilities in precision frequency sources: Fifteen years of progress
Precision frequency sources such as quartz oscillators, masers, and passive atomic frequency standards are affected by phase and frequency instabilities including both random and deterministic
Applications of the optical fiber to the generation and measurement of low-phase-noise microwave signals
The optical fiber used as a microwave delay line exhibits high stability and low noise and makes accessible a long delay (≳100 μs) in a wide bandwidth (≈40 GHz, limited by the optronic components).
Artifacts and errors in cross-spectrum phase noise measurements
This article deals with the erratic and inconsistent phase-noise spectra often seen in low-noise oscillators, whose floor is of the order of -180 dBc/Hz or less. Such oscillators are generally

Theoretical variance #1 ("Theol") has statistical properties that are like "Avar" (Allan variance), with two significant enhancements: (1) it can evaluate frequency stability at longer averaging times than given by the definition of Avar, and (2) it has the highest number of equivalent degrees of freedom (edf) of any estimator of frequency stability.

The action of modern high-resolution frequency counters is elucidate by consideration of their operation in the Fourier domain, and it is demonstrated that the difference between the actual Allan variance and that delivered by these counters can be very significant for some types of oscillators.
Oscillator metrology with software defined radio.
It is demonstrated that, generically, commercially available multi-channel SDRs are capable of time and frequency metrology, outperforming purpose-built devices by as much as an order-of-magnitude.

The close-in AM noise is often neglected, under the assumption that it is a minor problem as compared to phase noise. With the progress of technology and of experimental science, this assumption is
Phase-Noise and Amplitude-Noise Measurement of DACs and DDSs
This article proposes a method for the measurement of phase noise (PN, or PM noise) and amplitude noise (AN, or AM noise) of digital-to-analog converters (DACs) and direct digital synthesizers (DDSs)
