Hi,
I measured a blackbox at one frequency and many different states (with a network analyzer). With the resulting S-Parameters (for every single state), i can describe this blackbox. The parameters of interest are only the input reflections (S11). Here is an example of the measurements - plotted in a smith chart:
**broken link removed**
Every single point is a complex value with a real -and imaginary part.
Now, I want to get the maximum output power of the blackbox for the measured states.. I have more than 3000 values and i dont want to measure at every single state to find the maximum output power, so i want to use the nelder mead method.
I think that i understand the method and have an idea, how to implement them for an automatic measurement system. My only problem is to find the 3 start values. My guess is, that it does no matter which values I choose, because at the beginning of the first triangle, the algorithm is looking in every direction to find the value with maximum output power of the blackbox. Is it right? I would prefer to start with the minum and maximum of the absolute imaginary part and maybe the half of both for the third point. Or are there better suggestions?
Regards
