how to compute the phase noise in ADS and display it?

[bleuame]

I want to know that how to compute the phase noise in ADS and display it when we design a Voltage Controlled oscillator.

I have a VCO simulation now, i want display the figure of phase noise VS noise frequence or operating freq, but i don't know how to do it!

Thank you!

Re: how to compute the phase noise in @DS and display it?

I only know that you can use "Oscport" in the ADS to measure the phase noise.
I don't know the detail of it.
Do anyone know it?

Thanks
