Well, thanks for the advice! ...And also one other convincing (at least for me) feature:
The M12+ has a choice of either a 1PPS precise signal or a 100PPS precise signal. For my application (GPS disciplined frequency standard), the 100PPS option will surely help settle the frequency for the few seconds after turn-on/reacquisition. But i saw a line, i'm not sure about: (specs for the M12M, the replacement (starting july 2006) of the M12+ Timing accuracy: Performance using clock granularity message: Better than 2ns, 1 sigma Better than 6ns, 6 sigma Performance NOT using clock granularity message: Better than 10ns, 1 sigma Better than 20ns, 6 sigma What's that clock granularity message? For me, It looks like a message telling the actual error of one particular 1PPs pulse. Does it sound right? And also, how do i know or decide the actual error range (1 / 6 sigma) Thanks all! --- [EMAIL PROTECTED] wrote: > > From the leapsecond.com website, it seems the > Trimble gets 2.15E-011 at > 1000s intervalls. > > The M12+ achieves 2.9E-012 at 1000s intervalls. > > The M12+ is speced at 10ns 1-Sigma, the Trimble > seems to be 15ns at 1-Sigma. > > There is an M12+ follow-up modell comming soon which > is even better than > this data. > > Then there are the curious spikes that > leapsecond.com mentions... > > Seems the Trimble is significantly worse than the > Motorola GPS? > > bye, > SJ > > _______________________________________________ > time-nuts mailing list > time-nuts@febo.com > https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > __________________________________________________ Do You Yahoo!?
