If pressed, I would estimate less than 100ps. The error of this measurement contributes to the error in our final measurement which has many components. I haven't worked out an error budget for each contributor. Our goal is a final error of less than 10ns.

Clock Composition by Wiener Filtering Illustrated on Two Atomic Clocks - about clock ensembling using estimator - advantages over PLL&FLL (+ case study) - much simpler in LTI case over currently used Kalman filters 2.

Year of manufacture estimated 1984/85, from date code on ic's. I notice that the tube is from FTS, the same construction as in the FTS 4060, but different part number and wonder if this was original fitment, or has been replaced at some stage... Regards & Thanks Chris Quayle Oxford, England .

The timing report and estimator is just to make sure that a synchron design will work. The type of jitter/noise that you see is kind of typical. It's not that I don't like FPGA, I love it, but I just don't trust it for precision timing like that. Cheers, Magnus

Ole's estimate of 1-2k/yr is much closer to the truth than your $161/yr. /tvb

What we call "carrier phase" is just using the information from that subsystem to get a better estimate for the time differences. Attila Kinali -- It is upon moral qualities that a society is ultimately founded.

. > However, if you're going to post process data using something like Gipsy-X, they have "better estimates" of the time base for all the systems, so you can get a combination. I suppose when you process you tell it which one is your favorite base, and it adjusts to that.
