[time-nuts] Bad date out of HP Z3805A

I have used a HP Z3805A for my shack for a number of years. I recently wished to get the date output. Hooked up my laptop, and found that while I had a stable, in spec 10 Mhz output, I now have a date of 3/17/1996. I did a system reset, and a new survey. The date on startup is 1/1/1996; It

[time-nuts] Z3801A and FE-5680A Allen Variances

Would someone familiar with the facts please report the long-term Allen Variance of the HP Z3801A and the FE-5680A. -- Best wishes, Larry McDavid W6FUB Anaheim, California (SE of Los Angeles, near Disneyland) ___ time-nuts mailing list --

Re: [time-nuts] Z3801A and FE-5680A Allen Variances

Hi Without being at NIST, there is no real way to report the ADEV on the 3801 past 100K seconds. They change ADEV in the 1K to 20K region depending on the state of their internal filter. They should be below 1x10^-13 under most conditions once they get past 50K seconds. This all assumes the

Yes, you are missing 1024 weeks. Google: GPS week rollover. --- Graham == On Sun, Nov 1, 2015 at 7:19 PM, Charlie wrote: > I have used a HP Z3805A for my shack for a number of years. I recently > wished to get the date output. Hooked up my laptop, and found that
