Are you sure you want or need a PC-based card for this? This sort of precise calibration is often much easier with a simple frequency or time interval counter. Have a look at: Clock Powers of Ten http://www.leapsecond.com/ten/ 1.8 ppm frequency error in a Junghans WWVB radio clock http://www.leapsecond.com/pages/Junghans/ Decoding WWVB atomic time radio controlled clock http://www.leapsecond.com/pages/sony-wwvb/ /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
