I'm have a really hard time figuring out how to use ADS to simulate a 2-tone response to find out an amplifier's IM2, IM3, IIP2, and IIP3. I can't find any good resources on the internet to explain how to do this (and any ADS guides I've found are too vague/generalized and don't go into detail for this).
So, I have an amplifier and added a V_nTone block at the input. I added the Harmonic Balance simulation block and specified the fundamental frequency and the desired order. When I try to simulate, I get an error saying that the maximum allowed frequency difference is 1 kHz (my 2 tones are each 1 MHz away from the fundamental), so ADS doesn't so the HB simulation. How do I correct this?
Also, once I get past the above error, how would I plot the IM terms? Is there a certain function to do this?
Thanks in advance.
