hi,
I am designing a stack inductor.
The problem is how to test it. The common way is to test the inductor using network analyzer.
But also some guys using a VCO to test Q of the inducor ? Does anyone know how to do this ?
Thanks
Gang
If you have a lab kit of capacitors that you know are likely to be way better than your coil (ATC A or B for instance), then I would make a parallel resonant circuit with your coil (to ground) in the band of interest and measure the resistance at resonance. Not perfect, but it is hard to argue with the simplicity. Again -- this assumes your capacitor contributes little to this resistance.
