Hi Dave,
Your email is working now? I read in forum his email was worng. I tried send emal two times but notl answer. Delay between two mail several weeks.
Many expert help me a lot. Including you, on nanovna forum, your webpage, Kurt and others.
Kurt share very detailed calibration standard conversion from wvna to nanovna. For unkown oslt also included manual. I will try understand it.
I have calibration errors. I use coaxial line test. I not know why. I try use Kurt calibration values. Maybe my calibrators different or other errors exist.
Can you mesure/caracterize your nanovna calibrator? s1p files interesting to.
I not have gold standard and well calibrated device.
