Since you use s6p Touchstone s-parameters file and they have no information about Noise of 6-port device, it doesn't make sense to add a Noise to Power Source..
You confuse essentially small signal and large signal analysis.I have repeated many times here, s-parameters are small signal network parameters and they don't include any information about nonlinearity of the circuit so using of HB is nonsense.. You can do transient analysis to observe port voltages and currents but HB is done to essentially predict the nonlinearity of the circuit.So applied voltage/current will exit as linearly but with no harmonics.
Since they have no information about circuit's noise, adding a noise information to the Port will not work..
Thankyou for swift response,
Yes, maybe thats the reason i am not getting any effect on the output voltages even though i am adding phase noise or non linear noise present in HB.
Actually i am sweeping phase in one of the P1tone (simulating phase difference between input signals) and then computing I/Q signals from the output voltages and from them i am calculating the measured phase difference.
I wish to simulate some noise effect at source, to see the effects on my output voltages (I/Q signals).
Can u please suggest what kind of simulation i should use and how to add noise.
Thankyou

Thankyou @dick_freebird and @bigboss for rapid and valuable responses.
I am just using P1tone as two power sources feeding into a .s6p symbol that has four output ports. I am using voltage signals at 4 output ports to give me I/Q signals. From I/Q i measure phase difference between input signals
i need to simulate realistic noise environment which can have some deteriorating effects on the output I/Q signals.
Can you please suggest which simulation controller can be added in ADS and how a noise environment can be simulated. Maybe some noise block which adds noise in P1tone power source.
Thankyou very much
