Hi Maximo,
The calculation you need in order to produce series impedance is this:
Z = 100*(1-S21)/S21
Note that these are all complex values. If your VNA has built-in math
capability, use that. Otherwise export S21 and do the calculation in Excel. Be
sure to check your calculation by measuring something simple like resistors and
maybe a known inductor. Measuring high-value resistors will also demonstrate
the limitations of your test setup.
