Hi Tom, 2008/10/3 Tom Van Baak <[EMAIL PROTECTED]>:

This does show that for a long sampling time, quite a high degree of accuracy could be obtained. The downsides are that the sampling period would have to be very long and could easily be affected by power cuts causing failure to my proposed testing method. So theory proved but impractical. Looks like I'll have to bite the bullet and go with a GPS disciplined ocxo to make a good frequency standard.
