CST - Seeking help to realize power excitation in Frequency domain solver in CST

Dear Altruist,

I am running the frequency domain solver in CST and every running the simulation I can see stimulated power from the waveguide port is 0.5 W. Is that normal in frequency domain solver to have 0.5W stimulated power from such port? ( In time domain I think it is 1W by default). How can I change it to 1W. Help guide me step by step. Could you please help me to realize is it normalized power or not, How can I realize it?

Your help will be highly appreciated
