Hi Everyone,
I found a nice program for some tasks (linsmith)
http://jcoppens.com/soft/linsmith/index.en.php
but it states from the very beginning "The chart works in real impedances (not normalized ones)" Still the chart looks identical with the usual ones, 1 in the center and so on.
I run a sweep with a .csv file of impedances I had at hand and it seemingly works, but I am not clear how to interpret the results.
I don't know now, where is the Z=50 Ohm in this chart

does anyone know how I can deal with this non normalized chart?
A lecture hint perhaps?

thanks,
Gelu

Yeah,
sorry for bothering; The program deals with raw data and normalizes the impedances by itself, but that statement at the beginning, for me as a non native was a bit cofusing.
While importing a .CSV wit about 200 lines, was not able to correlate but after inputing some well known values I realized that . Z=50+j0 appears on center, Z=100+j100 apears at the intersection of circle of constant resistance noted 2 and the curve of constant imaginary noted 2.

SOLVED
