Charles, I find it hard to believe that an engineer with your obvious skills would even need to question the fs issue or ask questions about it's truth. Even the briefest glance at the block schematic shows that there is a 100kHz filter in the loop which would limit the lock to 10us given that

OK, I'll give you that. But, how does it account for the rapid change in slope, or the abrupt change for that matter? It doesn't look like an aging crstal to me (maybe one with a problem that jumps in freq). For the most part, there is no jumping DURING the slope, it seems to change on the

Charles Posted a bunch of stuff (below), Most think I should just ignore him, but I can not help myself, he has after all made this one just too easy and silly not to respond to. I hope Charles did not consider this to be just another good example of all the 'constructive helpful criticism'

I am thinking about trying to measure the aging process over the coming months, and then try to model and even predict future aging. If I can get that to work, perhaps I can even incorporate the formula for predicted aging right into my software. Any insights on this would be much
