Re: [time-nuts] Frequency counter questions

Do typical frequency counters start their gate in phase with the incoming signal? I guess the answer would be, "It depends." I was just thinking about how I would program the STM32F7 counter I am designing. btw, Gilbert, a local time-nut, sold me a 5335 today so I will be able to buiild

[time-nuts] HP 5061A Cesium Beam Reference For Sale

Hello Time-Nuts, I acquired a number of 5061A and 5061B chassis (some with tubes, some without) plus a number of tubes - all in various states of unknown working condition. After going through the tubes to find working ones I have started to piece together working units. I currently have a

Re: [time-nuts] Frequency counter questions

Hi Keep in mind the previously stated limitation - Your GPSDO is only just so accurate. If you *could* read 0.001 Hz on a 100 MHz signal in a second, the GPSDO would not be anywhere near good enough as a reference. Keeping track of that sort of stuff is one reason a lot of companies train you

Re: [time-nuts] Frequency counter questions

So the STM App note An-4776 teaches how to use an external clock and it looks pretty accurate in implementation. I’ve read thru the code and it looks easy to implement. Now I just need to bring another signal in and count it. I’ll be working on some code this afternoon to implement the

Thanks Rick, I understand better now. The turn over label is still on the crystal but not the matching label on the PCB. So far I've not been able to get the software to run but will try with some older versions of Windows and see how it goes with those. Nigel GM8PZR In a message
