I've investigated several Q measuring methods. Appended to: is using Voltage Ratio. DG1032 used as generator and Oscilloscope used as a RMS voltmeter. An Oscilloscope is not normally a good voltmeter, but is what I have. I did not expect an exact match to BW Q measurements, close.
Possibly inspire a micro-controller two channel Vrms meter with greater accuracy.
As Q increases, voltage measured across series LC will decrease, limiting measurement range depending on Vrms meter range.
For this measurement, measured Q is both L and C. As always, C Q is necessary to isolate L Q.
