But that brings us back full circle: How do you do an exceptional job of controlling the temperature of a crystal that was designed to operate at 25C? You cannot just leave it in a room temperature box, and expect it to remain stable. You need to mimic what is done with a conventional double oven, only with an "ambient" temperature that is well below the desired operating point of the crystal. The Peltier would provide that reduced "ambient" temperature. I read the article you are talking about, and what he says is true, to a point. He is talking about maintaining the stability of instruments that are designed to run at room temperature. These instruments already have conventional double ovens around their sensitive bits. -Chuck _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
