HSPICE RF mixer simulation problem

[princeattrey]

Hi guys,
I am new to HSPICE and today i am trying to simulate a RF mixer based on GNRFET but i don't know how to calculate power and frequency of the output node. I want to draw a plot between output power in db and frequency of the output node. So can anyone help me with the command for doing it. Thank You in advance
