Re: saving measurements from nanoVNA

 

What AA6PZ said.??

In practical terms, find a frequency where the reactance is between 25 to 100 ohms, and do the math.? ?


To take the math a step further:

Z = 50?¦¸?. (1?+ S11) / (1- S11).? ? ? ?

The real part is the real part (ohmic).

If the imaginary part is positive, it is inductive, and the imaginary part is j¦ØL.

And if it is negative, it is capacitive and the imaginary part is 1/j¦ØC.

Some VNA's??you this directly.? ?NanovnaSaver will:

Simple

Use the nanoVNA to measure impedance. Take one of the following formulas and a little algebra to solve for C or L.
