  • Build a 10MHz Rubidium Frequency Standard and Signal

    Aug 03, 2013· Build a 10MHz Rubidium Frequency Standard and Signal Distribution Amp for my Lab By gerrysweeney on August 3, 2013 December 23, 2018 51 Comments Having gotten myself a Rubidium Frequency Standard I found that the unit on its own is not that useful, its really just a component and needs really a supporting PSU and a decent enclosure to make itI wanted to build a 10MHz frequency reference for some time now Because I can't easily get my hands on a Rubidium frequency standard, a GPS derived reference seems like a good alternative This was inspired by YouTube videos by Gerry Sweeney and Scullcom Hobby ElectronicsGPS locked 10MHz lab frequency reference | Hackadayio

  • 10MHz Rubidium Standard | Hackadayio

    I wanted to give my Rubidium 10 MHz oscillator a nice home Some addons would be nice, also particularly a distribution amplifier for the analog 10 MHz reference outputs A set of CMOS outputs would also be helpful Finally, I really like my homebuilt comb generator, so why not build that in and have an accurate comb source for RF work? I repurposed a broken Harrison Labs power supplyPerformance of the 10811based Thunderbolt is nearly on par with one of leapsecond's best Z3801A clocks, at <1E12 at all offsets The magenta trace is actually limited at timescales below 10 seconds by noise from the HP 5065A rubidium standardNotes on Trimble Thunderbolt performance and modifications
