Hi One suggestion on the frequency plot: TimeLab as you have it set does a “per pixel” process on its charts. You have a limited screen resolution and a ton of data. You have to do something. There is no way to display it all. It’s a good idea to zoom in to some of the “problem regions” and

Hi If simulation is going to be precise, you need a pretty good noise model for all of the various things that get in the way. You can come up with those models, but it isn’t going to be easy. Generally, once you get the device running, you switch to working with it rather than doing simulation.
