I haven’t found a good tutorial on this yet but here’s an app note on amplifier testing. http://www.cleanrf.com/images/CleanRF_Manual.pdf
Though this is for a system different than what we are doing the pictures on pages 10, 11, and 12 illustrate what to look for. The “overmodulation” picture on page 13 is not what we would see for >100% since this shows a different type of distortion.
If I find something better I will post.
