Hi John, but you may not be comparing apples to apples. Tom's plots are actual performance of probably a very good sample unit. The 5071A spec lines you drew are worst-case specs. In reality, the 5071A probably performs much better than it's spec limits? Also, I think the 5071A "just" has a good 10811 OCXO in it as well, so the short term performance of the 5071A is probably limited by that OCXO. bye, Said In a message dated 12/10/2009 17:48:57 Pacific Standard Time, [email protected] writes:
It's interesting to consider how well a GPS clock can perform relative to a local cesium. I took a plot (attached) of a Thunderbolt with a 10811-60109 (t=850s) and one of the sub-$100 LPRO-101 rubidiums, then drew some lines on it to indicate the spec limits of one of the better cesium standards (the HP 5071A). I also tried to copy the traces from Tom's Z3801a at http://www.leapsecond.com/pages/gpsdo/ onto the plot. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
