Convert Inductor's VNWA-s1p data to inductance.

Explanation of how to calculate inductance from extracted VNWA s1p data.

Import the VNWA data of the frequency characteristics of the coil into EXCEL.
This is a plot of a 1μH coil on an S11 Smith chart.
Explanation about extracted s1p data.
This is an image of a spreadsheet created to measure the S11 of a 1 μH coil using a Vector Network Analyzer (VNWA3E) DG8SAQ, import the S1p data into Excel, and create a frequency response graph.
Calculates the phase of the reflection coefficient.
