Hi Warren, that's a smart idea. It's fun to try different OCXO types out for their individual sensitivities. I have seen some that are only sensitive in one single axis, others that react on several axie. To take your concept further, one could also orient the OCXO to minimize the effect of vibration as well (caused by e.g. power supply transformers, fans, walking in the room etc). If I read the post correctly, someone said they can literally "talk" to their DRO, and make the voice come out of their Spectrum Analyzers FM demodulation loudspeaker. After all, crystals are quite microphonic as well. bye, Said In a message dated 8/15/2009 09:46:46 Pacific Daylight Time, warrensjmail-...@yahoo.com writes:
When possible, the thing I do to eliminate the effect of small gravitational changes or tilt from effecting the Freq of my Oscillators, is to orientate their case so that the osc is approximately at its MAXIMUM 2G turn over axes. This gives the osc a null to small gravitational changes, much the same as setting the temp of an oven to the zero TC freq turn over point. To optimize further, the axes can be fine adjusted so that a small tilt in any direction causes the same direction in freq shift. The improvement achieved can be quick substantial like 100 to 1 improvement. ws _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
