does PAC sim cover transfer function on carrier itself

Hi,

In a system that amplifies or attenuates input depending on the frequency and input is a single tone clock (no modulation), If the goal is to find out the transfer function from input to the fundamental at the output vs. input clock frequency, Can I use PAC sim?

My understanding is it doesn't apply as there is no small signal here, if so, what sim will do this \other than multiple transient sims

thanks,

Kevin
