Hi Herb, very nice Battosai42.
I did something similar a long time ago using the old school hp vector voltmeter.
One question on the displayed result example. The Co value shown of .56 pF. Seems awfully small. Does he remove the package C somehow in the measurement and calculation or is this just the Co of the xtal blank? That particular package has to have a larger Co than 500 fF. Typically that value is picked off by moving well offset from the series resonate frequency of the xtal.
