| JRoberts | Aging time base crystals | For what it’s worth, I’ve never heard an engineer complain about this as a problem. That’s just my own experience and I know it doesn’t mean a lot. With clocks and watches the inaccuracy would be cumulative over time. The error/second would be multiplied by the number of seconds in, let’s say, a month. I also know that there are varying grades in quality for quartz crystals. You would think that an expensive instrument would use the highest quality available, compared with inexpensive clocks or watches. A better quality crystal probably maintains its spec. frequency over a longer time. |

| Rayman0723 | aging quartz crystal oscillators | I agree with JRobert. Top quality crystals are probably < $10 purchased in quantity. When that’s the heart of an instrument costing hundreds or thousands I’m sure they would use the best. |
