How can i measure inter modulation distortion of a RF Mixer circuit in ADS?

I have designed a RF Mixer circuit in ADS. I have taken the parameters like gain, conversion gain and 1dB compression point. Now can anyone suggest me to take IID in RF Mixer?

There are multiple ways to run a simulation to find the IMD. You can go to Insert>>Templates or go to DesignGuides>>Mixer DesignGuide

Take a look at this tutorial:
