It was used in the HP 8566B Spectrum Analyzer for a while at least. So whatever the 8566B specified for its OCXO would be a minimum. I have a dead* one here from my 8566B. The pins are wired to a connector with the following colors: 1,2) Black 3) Red 4) Purple 5) Orange 6) Black No EFC to my

[time-nuts] FPGA card with two 10MHZ inputs, and two 1 PPS inputs?

2021-04-13 Thread Anders Löwinger
Hi! Is there anyone that can recommend a Xilinx FPGA PCIe card with a XCVU9P in a standard PCIe formfactor, which can receive two 10MHz and two 1PPS (from two different frequency sources). The 10MHz needs to be connected to a Xilinx Global clock register, the 1PPS is fine with a standard

On a hunch, I searched for the other part number on the nameplate (0960-0477) in one of the military stock reseller's database and found that the only end item that this oscillator was used in was the AN/FPS-115 PAVE PAWS (Precision Acquisition Vehicle Entry - Phased Array Warning System) radar

Hi Since this is a part that Ovenaire made for HP, probably the best way to work out what’s what is to find the equipment that it went into. Best guess is that would be an item that shows up in the 1985 ~ 2005 HP catalogs. ( = OSC92 is an Ovenaire part number that was carried on after McCoy

Russ, You could have also just run gpedit.msc (group policy editor) to turn off the updates/reboots in windows 10. It comes standard on pro but can be added to home also I believe. Kevin ‐‐‐ Original Message ‐‐‐ On Tuesday, April 13, 2021 9:56 AM, Russ Ramirez wrote: > I have

Ubuntu server is great - I’ve been supporting applications on Ubuntu for over 10 years now and it is easy to maintain and update. Set Ubuntu up absolutely minimally - no packages installed unless absolutely necessary. Certainly no X11 or GUI desktop. This way the number of security updates will

I have been running a Windows PC with Lady Heather and Meinberg NTP monitor for 6-7 years now. One very annoying problem with Windows 10 has been the forced updates and reboots knocking my headless configuration on it's arse. So I have been experimenting with various Linux options, first with RPi

Tom I remember the pictures of the unit. But perhaps did not realize that you actually purchased or own the unit? Now that would be one heck of a job to clean up. Would guess the C's are very very long gone. Although the video sent was interesting to see how they just dumped the Cs capsule in. It
