This video briefly explains how to influence a crystal oscillator’s frequency by introducing reactive elements such as trim capacitors and inductors. This example uses a very simplistic Pierce oscillator and a crystal ins series resonance.

Hi,
That was a very good informative video on pulling crystals – Congratulations!
BUT …. unless you were talking about joking/insincere/flippant xtals, the word you wanted was “series” not “serious”
A little grating to here “serious” repeated so many times
none of us are perfect!
Cheers,Jon
Oops!
“hear” not “here”
as I said – none of us are perfect!
