Ken I recently saw an issue with oscillator reliability that had nothing to do with handling. Certain FOX oscillators have a MINIMUM power rise time of about 15 milliseconds. Power supplies that came up faster than that caused uncertain results. Has someone switched suppliers in an otherwise mature product?
