<snip> Both Meinburg Funkuhren and Symmetricomm offer PCI cards with "super clocks". An Oven Controlled Crystal Oscillator (OCXO) is available on these cards for a premium price. The oscillator can, I believe, be GPS disciplined on either card. Be prepared for "sticker shock"! These cards cost around $1200 US the last time I looked and they may cost more now. I have occasionally seen them for less on e-Bay but that's not something you can count on finding when you want it. _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
