Transformer/inductor design Part 3
This measurement setup is very WRONG, signal feeding from a too low impedance for parallel resonance.
On this site you learn how-to-do-it the right way.
That is feeding the signal with a TOP-C with a value of 1% of the parallel Cap or less, down to 0.1%.
In this way the Q damping by the signal source is minimal and what you measure is more realistic.
