Dave,
I've let the board collect ntp data for ~24 h and then using that data I was able to adjust for the constantan drift. (I'm using the following client http://doolittle.icarus.com/ntpclient/ that is based on xntpd), during the test runs I also gather other statistics that will give you a fairly good idea of how good your boards time is. If you follow their instructions I believe you are able to get to 10 ms accuracy, my board seems to be able to get close to that. I'm synchronizing two radars with 1000Hz prf hence I need sub millisecond accuracy so they can point at the same volume. But then read Ian's comment and it doesn't look promising for us…

Thank you all for your inputs, I appreciate them.

OK, So we are attempting to do pretty much the same thing ( I think ). How do you generate a timed event to sample, or do you ?

Dave
