Agilent ADS : determining impedance @ one point ??
That was my first approach, in fact.
But I noticed that the impedance depends on the value of the impedance of the port.
If I put a 50 ohms port, I got a value, and with a 10kohms port, another...
... maybe a denormalization problem I don't understand ?
Edit: I understand the reflexion coefficient depends on the source load, but I do not, when I'm looking in the Smith chart: if I understand well, the displayed value is normalized to the input port value, so it should not change ?
Where the hell am I wrong ??
Added after 4 hours 5 minutes:
... sometimes, searching worth the price you pay for
When you start the simulation, then obtain the Smith chart, then after mark for a certain frequency...
... then left double click on the info box (with frequency you picked up), goto Smith tab, and select which Z0 you're using !
By default, "normalized".
There was my problem !
Hope this could be useful for somebody else
