After I got disappointed from my impedance meter (for measuring inductors) I decided to try and build one on my own. I was encouraged by the ability to measure inductance (actually calculate) accurately using a simple LC tank. The problem with this method is that a very large range variable capacitor is not available and discrete capacitor matrix will be somewhat limiting and overly complex.
The parameters I want to have at the end are: inductance, impedance (real and j), Q. As far as I see I only need the inductance and impedance to calculate all the other parameters. The question being asked is what method can be used to measure these at variable freq. ?
