== Phase Noise Tutorial ==

[[attachment:Low-CostPhaseNoiseMeasurement.pdf|Wenzel: Low-Cost Phase Noise Measurement]]. Quietly the best phase noise tutorial.


Here is a brief tutorial (by Alex Mott) on how to measure the phase noise of an oscillator: [[attachment:PhaseNoiseDocumentation.pdf]]

== Representing Phase Noise ==
{{{
dphi_rms(f) [rad/rtHz] <=> 20 log(dphi_rms(f) * sqrt(2) / 2) [dBc/Hz]
}}}

{{{
dphi_rms(f) [rad/rtHz] <=> (dphi_rms(f) * f) [Hz/rtHz]
}}}
