Conceputaly, you may consider like following.Is port acting as input source with some power?
Conceputaly, you may consider like following.
For s11 and s21, port1=hot, port2=cold
For s12 and s22, port1=cold, port2=hot
Too easy thing except for you.I want some simple and clear explanation.
Too easy thing except for you.
Calculate Y-parameter, then convert it to S-parameter.
Study and learn how to calculate Y or Z parameters.
ADS stimulate the circuit with a very low signal level by default s-parameter definition even there is no field for signal spec..That's it you don't understand..I think you have not got my question. I know about S, Y and Z but here my concern is how "term" is used to calculate it. I mean here I have not define any signal in "term" componant e.g vtg level, power level etc but still I am getting output. As per my knowlege concern, if you dont give nay input to DUT then you should not get any output.
You can not understand them at all.I know about S, Y and Z
It specifies reference impedance.but here my concern is how "term" is used to calculate it.
Any stimulus signal is not required for calculating Y or Z parameter.I mean here I have not define any signal in "term" componant e.g vtg level, power level etc but still I am getting output.
Surely learn kindergarten level linear circuit theory.As per my knowlege concern,
if you dont give nay input to DUT then you should not get any output.

You can not understand them at all.
It specifies reference impedance.
Reference impedance is required for S-parameter.
On the other hand, Y or Z paramete don’t require reference impedance.

Still you can not understand things correctly.Do you know what is default value of low signal ADS using to simulate circuit?
That is what I was asking. Do you know what is default value of low signal ADS using to simulate circuit?
Wrong.S-parameter simulation is a subset/kind of AC Simulation
so there is a very low level stimulus but hidden.
Otherwise simulation will not run without no source condition.
Wrong.
There is no stimulus signal in S-parameter Analysis.
Any hidden signal does not exist.
Assume circuit with many ports.
If we do analysis with changing port exciting, it is too uneffective.
Any stimulus signal is not required for calculating Z or Y parameters.
Here we don’t have to calculate any node voltage or branch current.
Wrong.Simulators use these specifications and NO circuit can be simulated without Excitation Source.
Wrong.
You are misunderstanding.
It is true for DC and Transient Analysis.
But it is not true for small signal linear analysis.
It is very natural, since you do AC analysis.If your hypothesis is correct, this circuit should have been simulated by ADS but gives an error..
Wrong.Any circuit which the Sources are not Existing cannot be simulated,
it's controversially against the Circuit Theory.
