Agree.? Measure it directly.? Using the method in the vid gives the capacitance inductance product, but not the individual values.? You still need to know the value of one of them to measure the value of the other.? Maybe the value printed on the capacitor is good, but it has a tolerance and may be off even more than that.? Plus, the test setup is adding stray capacitance and inductance that further obfuscates what you want to measure. No need to go back to the old grid dip days, except perhaps for nostalgia.

Agree on YouTubes too. On Sunday, August 15, 2021, 10:41:30 AM MDT, David Eckhardt <davearea51a@...> wrote:
Is everything these days a YouTube "presentation".? I'm not knocking what is presented, as the theory is sound and is rather reminiscent of the setup employed when measuring inductance with a grid dip oscillator, but a bit more accurate. Any of the NANOs can measure inductance (and capacitance) directly using the Smith Chart option and the Cursors.? Once calibrated, the inductor is connected across the source port directly, yes, both center pin and backshell of the connector.? It will be in parallel with that port.? Once configured, the value of the real part and the equivalent reactance of the complex port (the inductor) can be easily read in the upper left of the NANO display.? The NANOs can also be configured to simply display the reactance of the complex part directly instead of the equivalent value of the lumped inductor.? Again, just an absolutely wonderful instrument which compares embarrassingly well to the (expensive) HP/Agilent/Keysite VNAs.
