I have been looking at all of these OCXO's for sale on EBAY. Most seem to be coming out of China. It as if they are scrapping lots of equipment and pulling out the oscillators. There are lots of data attached to these auctions. It seems that for an OCXO the rate of aging changes with the period of time it has been running. Typically I see aging given in "after continuous operation" intervals of 30, 60, 90 days with a rate decreases as the period of time increases. So the questions: Is this a onetime 30,60,90 day burn in ? Or does this same information apply to an oscillator that's been on the shelf(or in China waiting to be sold) for say 6 months ? Does aging ever stop? Does it decrease at a slower rate? A lot of the oscillators on EBAY you can see the date codes. If there was a certain model of high quality, all else being equalize would you buy the oldest unit that might have the most hours on it? I have a Rakon Double Oven OCXO right now but there seems to be a few made by Oscilloquartz that look pretty good. However I don't see any OCXO's that use a Dewar like the FTS unit I had... Do they show up from time to time? Thank you
