A video I did up last summer on how to use the nanoVNA to measure the resonant frequency of crystals.
The intended audience is those who are not wanting a complete and exhaustive characterization of crystals, rather, a quick and simple method to take a handful of random crystals and to determine the resonant frequency so as to be able to sort and label said crystals. Also includes a simple explanation of parallel and series resonant modes of crystals.
