How to calculate the Noise Figure in CST MW Office?

Hi everybody.
I just made a 3 section chebyshev transformer into a rectangular waveguide. So far, so good, let's say I reach the specifications, and let's say it it coupled.

So, anyone of you knows how to calculate the noise figure with CST Microwave Office?

I think I have to program it.... but how? Maybe as a Post-process, with the S parameters. I don't know. Do you?

Hi ardiware
refer this for your information

You will get amplifier tutorials
where you will find how to measure NF in MWO.

ardiware,

CST Microwave Studio or AWR MWO ?

Oh yes... he he... sorry, I mixup the two softwares.
It it CST Microwave STUDIO.

And thanks for the help, Abhi~, that PDf will be helpful too, but I need to measure the noise figure in the CST MW Studio.
