Hi Rune,
thanks for the hint! I tried it out right away and it works very well!
I have attached the plot of a 200MHz BP-Filter. The calibration is done with full span and 8 segments. Now I can figure out the bandwidth manually.
One thing I would like to mention. For good reason the professional VNAs have "number of point" settings of i.e. 101, 201, 301, 401, 801 and so on. Could that feature be implemented in your software as well?
Kind regards
