32.768KHz tuning fork cut quartz crystal - stability
« on: November 22, 2016, 10:07:13 pm »
I am using this 32kihz Crystal, and my requirements need long term accuracy while I don't care about stability between pulses. Can I actually assume that the error caused by instability has a gaussian distribution? Ie, is it realistic to ignore the stability spec when speccing the drift tolerance of the clock?

Assume that I correctly calibrated the short term accuracy using a sample of a few minutes worth of counting clock cycles. Each unit is calibrated in production using an inhibition compensation technique.

If I just asked the wrong question, shame on me for asking before I was ready for help. Please be kind and direct me to a resource which will teach me the question I SHOULD be asking. Thank you.

I am duplicating this in meterology; my afterthought is that "Radio" wasn't the place for this question.
