FYI - I've been using a much simpler approach - just 2 turns of wire via the toroid connected to S11 input. Using 5 lines with math on s1p data...

@ Herman and Graeme and Holger - your hardware is definitely better than my 2 turns of wire, sure!! I saw a paper in past with the copper chamber as...

Here is the link to the paper [Permeability Measurement](https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjpyuSljYLsAhUMlxQKHfaYA24QFjAAegQIAxAB&url=http%3A%2F%2Fprzyrbwn.icm.edu.pl%2FAPP%2FPDF%2F117%2Fa117z522.pdf&usg=AOvVaw0AN7q-fldEfPZfic10o1a2) PS: this is a T50-6 (yellow Amidon powder toroid) measured with my 2 turns..  PPS: It looks too high for...

@ Herman - out of curiosity I've put my above s1p (T50-6 with 2 turns, 1-30MHz, 801 points) data into your excel table. I've added the "Turns Number" to the...

@ Herman - I've made 8 turns with my powder T50-6 core (mu=8 from datasheet). Below my measurement and the same data in your excel. Mine looks "feasible", yours a...

I've been coping with a bare wire antenna measurement.. Such a measurement would require de-embedding, imho. Btw, a "plug-in" nano-saver functionality would be "nice to have", thus people would be...

My math knowledge gets rusty, but I am pretty confident that "with _any_ values of the calibration data the measurement results will _always_ be positioned inside the SC space".

FYI - "3D Smith Chart" tool - https://www.microwavejournal.com/articles/33830-d-smith-chart-tool-is-now-free-to-all-students

The Smith chart cannot show data outside its border. It is like an o'scope screen.. :) Imagine yourself an oscilloscope screen - you may do whatever you want with its...

The Marker's information should update only when the sweep finishes, imho. It seems the Marker's information updates _during_ the sweep process, thus it messes up sometimes (or always)..
