Have you been able to resolve the followings.

You already implement differential current by using two "I_AC" in the above.
Turin wrote on Mar 18th, 2010, 4:01pm:but i'm not sure what to put in IIac=Polarpolar(x,x) and freqFreq parameters.
Iac=
polar(1, 0) and
Iac=
polar(1, 180)
or
Iac=1 and
Iac=-1
Here you can choose any "units" such as "A", "mA", "uA", "pA" and "fA" as well as "unitless".
"
Freq" parameter is used for FCAC(Frequency-Converting AC analysis).
Leave it default value, "freq" for conventional AC analysis like following.
Freq=freq (global analysis frequency)
Read documents of Agilent ADS surely.The followings are documents of Agilent ADS2009. But these are also valid for ADS2004A.

Is there any other way besides I_probesI_Probe?
We can save pin currents without inserting "
I_Probe" in current ADS.
But you have to insert "
I_Probe" since you use ADS2004A.
