Re: [time-nuts] Anyone have an HP5060A sitting around?

Somewhat available, the 'lab' is without power due to a complete house rewiring project. But if it just something I could do with a Fluke, I could help You can contact me off line ... -pete On Wed, Jun 15, 2016 at 9:48 AM, paul swed wrote: > Corby > Not sure I can help.

Re: [time-nuts] Anyone have an HP5060A sitting around?

Corby Not sure I can help. I have my frankenstein 5061 in a 5060 with home brew oven controller. I pulled the old controller out. Is it that you need measurements on the controller or with the tube also. If its with a tube I don't believe my measurements would be helpful. Regards Paul On Wed, Jun

[time-nuts] Anyone have an HP5060A sitting around?

Hi, I need a couple resistance readings at the A11 oven controller jack. Does anyone have one available that they could measure for me? Cheers, Corby ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to

Be also aware that there are outright fakes around. This one did not have any silicon inside. It made debugging very difficult. http://leobodnar.com/balloons/files/fake-M8030.jpg Leo On 15 Jun 2016, at 10:00, time-nuts-requ...@febo.com wrote: > Certainly cheap…. BUT > > On the ublox site

Re: [time-nuts] u-blox "naked" chips - anyone brave enough to try them?

Hi If you feed the chip with your local reference: 1) You need to synthesize a signal at the expected frequency (26 MHz, 48 MHz … whatever) 2) The signal needs to be low phase noise (per the chip set specs) 3) The signal needs to be constrained for ADEV (per the chip set specs) All of that

Re: [time-nuts] Improving on basic L1 timing

I should have added, if you do all of the above, the improvement in stability over just using a sawtooth-corrected PPS is not all that spectacular, a factor of two or three. I'll post a plot of some data tomorrow. Cheers Michael. On Wednesday, 15 June 2016, Michael Wouters

Yes, that's the seller. I think the firmware version is in one of the NMEA commands. -=Bryan=- > From: hol...@hotmail.com > To: time-nuts@febo.com > Date: Wed, 15 Jun 2016 04:37:13 + > Subject: [time-nuts] TU60-D120-131 Specs? > > Mine came from seller "electronics plus" in Michigan

Re: [time-nuts] u-blox "naked" chips - anyone brave enough to try them?

Certainly cheap…. BUT On the ublox site there is a table indicating that the KT is a standard precision engine. On the same table, the UBX-M8030-KT-FT is required for timing: < https://www.u-blox.com/sites/default/files/GNSS-Chips_Linecard_%28UBX-13004716%29.pdf > <

[time-nuts] TU60-D120-131 Specs....?

Mine came from seller "electronics plus" in Michigan (?) ... not sure of the firmware, all my machines are currently tied up doing other stuff at the moment. - Did you order yours from the same seller on Ebay.
