Help with measuring Phase noise.

[micktosin]

Hi There. I'm stuck on trying to measure phase noise from my spectrum analyzer. So can somebody please tell me the phase noise, from the attached pictures? In addition i will appreciate it, if you could explain how you measured it.



Please note both pictures gives the same values, the difference is due to adjustment in the Spectrum analyzer.

Thanks in advance.

Without knowing the type of detector you have in the SA, I expect a ballpark figure will be around -75dBc/Hz @ 1MHz offset. The type of detector will influence this measurement.
