Jerry, Thanks as always. That's very helpful, though ti adds a 3rd option to test.. This seems like a good application for 1-2 Farad caps on all the DC lines adjacent to the device being

This person named Adrian Rus, pretty sharp engineer and entrepreneur, (co-authored some papers with Ulrich) said (and we tested it) that you should have a minimum of 15,000uf on an individual

I am just starting on this project. So far all I have done is test 4 of the trimmer next to OXCO PCBs and measured the voltage required to set 10 bare OXCOs to 10 MHz. Tests on the first two PCB

Have you run a phase noise test on them? Sent: Wednesday, August 9, 2023 4:04 PM To: [email protected] Subject: Re: [qex] [Question] CTI OSC5A2B02 OXCO module high precision frequency reference

As a consequence of a completely unrelated conversation I got the idea of comparing the OXCOs to a GPSDO or another OXCO by filtering out the harmonics, mixing with a GPSDO, filtering out everything

A few general comments about how I intend to pursue this: 1) To the maximum extent possible I'm going to use comparison rather than measurement 2) I'm going to build the project in the smallest

You can look at some papers

i"m gob smacked! In the 10 years since I got into the topic I've never run across anyone other than an couple of oil industry friends who knew anything about it. Foucart & Rauhut is rather heavy

I worked in the field of compressed sensing and I taught a course that included this material. I also wrote several papers on compressed sensing instruments. I am very familiar with the works of

In general I strongly advise against jumping ahead of me to bring up some point such as the problem being illconditioned unless you have read and understand Foucart & Rauhut and "Random Data" by

I've abandoned originating posts on other lists. It's too hard to keep track of the discussion as evidenced by 2 on EEVblog and the most substantive on the HPAK repair list.

There are already two threads on Eevblog. Another one here? Best regards, Harke

I've bought 20 bare modules from this seller: https://www.ebay.com/itm/266143027936 Still waiting on the 2nd batch of 10. This is the pattern of the PCB version I

Reg, I would like to try out some of these OCXO's. Can you recommend an EBay seller? Mike N2MS

You might need to consider some kind of chopper-type amplifier for stabilizing the voltage at those very low input offsets and microvolt-ranges over long time scales. Otherwise drift is going to

FYI This is a repost from qrptech. I'm reposting this here so I can consolidate threads I start in one place. I've had people on one list bring up something I mentioned on another list and it's

This thread is really aimed at the component & PCB level issues. So I'm moving Pascal's SSB issue to its own thread. Have Fun! Reg

Perfect!
