I use "I[1,0]" for describing nonlinear relation between V and I.
But I don't use "In[1,0]" for noise expression.
Instead I use "I_NoiseBD" parallel to port-1 of SDD1P.

I use the HB simulator to simulate the steady state of oscillator, when I activated the noise simulation, I Have HB.freq and HB.noisefreq, I know that I can use only freq in weighting factor.
I want also to simulate the phase noise so I implement the Low-Frequency noise sources in the transistor (these sources are cyclostanionnary i.e. dependents on time), so the Dc current must be replaced by the instantaneous current.
"freq" and "noisefreq" are both system variable in Agilent ADS.
But you have to use "freq" even for noise expression.
Simply consider noise simulation of RF-RX mixer, "noisefreq" is set as IF frequency.
But noise frequency of RF input is not "noisefreq".
