I am not sure that a precision clock will help if the cpu is busy and skips clock cycles. I believe this is one of the problems with general purpose OSes like Windows.
I believe the better boards like the Soekis use hardware dividers to alleviate the cpu busy problem.

I'll probably end up with a used dell or IBM workstation for this purpose. Recently, I came across a low-cost frequency synthesizer capable of using a 10mhz frequency reference (planning on using the thunderbolt GPSDO I'm working with once I manage to sort out the temperature issues) http://www.tapr.org/~n8ur/Clock-Block_Manual.pdf ^ TAPR "Clock Block" has an installation example for how to do what I'm planning with a Soekris net4501 low-cost / low-power embedded device... What I'm hoping to figure out is how to do the same, except on a proper computer such as the local used ones I'm able to get for less than $200 with 2ghz with 30GB hard disk, 512mb or more ram, etc. So I figure this should be fine for what I'm planning. Example of what I'm trying to do, though based on the low-power embedded Soekris net4501 system from the TAPR manual's example section: http://www.febo.com/time-freq/ntp/soekris/index.html ^Aren't those the photos from clock block frequency synthesizer manual? Again, I'm wondering if anyone has opinions or experience about doing such things with NOT an embedded system (as I said, can get a nice 2ghz or so machine for less than $200 locally at a brick and mortar shop within walking distance) Thanks in advance, Sarah _______________________________________________ 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. _______________________________________________ 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.
