Hence, VQ in volts equals the inductor’s Q. This simple analysis assumes that the
range of CV is adequate to resonate with L.
If resonance is not possible within the working range of CV, then, depending on whether we are dealing with an inductor at the lower end of the range (90nH) or one at the upper end of the range (130 mH), we can add a known, standard series inductance in series with the unknown inductor, or a known, standard capacitor in parallel with CV, respectively.
The Boonton Model 260A Q-meter allows measurement of inductances 45 mH to 3%, and Qs to 5%.
