Very nice, Cecil. It would be also
useful to know how you obtained these
numbers.

I'm glad you brought that up. Here is the EXCEL spread sheet for that same
signal generator equipped with an auto-tuner. You are right in that it takes
a longer time to achieve steady-state but everything becomes completely
clear after 30 seconds and the results are exactly the same (using a 100
watt
signal generator).
