[time-nuts] FE-5680A Calibrator program by Bob Campbell VK4XV

2021-03-25 Thread DM
I've run across several references to a FE-5680A Calibrator program by Bob Campbell VK4XV, but searches for it have been quite unfruitful. Does anyone have a link to it, or know how to get in touch with Bob Campbell? I've searched for his web site, but it seems to have gone into never-never

Dear Attila We have clock comparison data going back 25 years so you could DIY. But I thought I sent that to you a couple of years ago? Cheers Michael On Fri, 26 Mar 2021 at 3:34 am, Attila Kinali wrote: > Moin, > > Does someone of those who own a 5071 have long-term ADEV data? > I'm looking

The ADEV of the 5071 follows the typical curve of improving at a constant rate vs increasing Tau until it levels out due to limiting by flicker. AFAIK, this flicker noise never turns back up. There is no observable aging either. Nor are there any observable environmental effects. The 5071's

Moin, Does someone of those who own a 5071 have long-term ADEV data? I'm looking for multi-year data. While there are plenty of ADEV plots online, most of them stop at 1Ms or even at 100ks. Background: I'm involved in a project where long term frequency stability is important. And I need some
