Multiple fundamentals in ocillator

[Lathas]

How can I check which are the fundamental frequencies present at the output of a multi-band oscillator using ADS simulator?

if u are modelling the oscillator alone and checking its performance at a termination, u are most likely to find peaks at various frequencies in HB simulation. Going thru a datasheet is a simple way to get the info on ur fundamentals which makes ur simulation much easier too in HB simulation.
