Hello,
does anybody know that which kind of jitter is measured by spectrum analyzer for the PLL and which kind of jitter is mostly reported in the PLL papers?
Thanks
most spectrum analyzers simply measure the power spectral density of the phase noise, and integrated it to show RMS jitter. On the average, it is an accurate calculation.
RMS jitter is measured in time domain,spectrum analyzer measures phase noise in frequency domain,it doesnot measure rms jitter directly.
As mentioned by biff44,they are one and the same thing but represented differently.For RF engineer phase noise makes sense,where as for
rms jitter is more meaningful for digital domain.
