Question about Zin and out?

Hello
For the circuit shown, Zin=100+1000=1100 ohm
Zout = 100//1000 = 90.9 ohm
On the Network Analyzer: Z11 = 11+j0, Z22 = 30+j0
How to relate the measured value to the calculated value

thanks

There's clearly something wrong with the tool or its application.

What S parameters [i.e. all four s11, s12, s22, s21] does the application give you?

I don't know how your simulated network analyzer works, but a real analyzer wouldn't like having a 10 volt source connected to the input port at the same time the analyzer is trying to make a measurement.

What do you get if you remove the 10 volt source when making the analyzer measurements?

But I think that voltage source must be disconnected as The Electrician suggested

its ok and the measured values exactly = the calculated
thank you alot
