It's unclear if this is a time source (i.e. you've got a grandmaster or such running PTP and sending time, and this widget receives it and puts out 1pps.  Or can it be a sender - I cobble up a bunch of stuff from my collection of masers and fountain clocks in my underground lair, and I can send that highly accurate tick to the rest of the (connected by cabled ethernet) world?

beaks out 1pps is ambiguous

Hi Paul,

Yes. I think the presentation on the web leaves a little more to desire,
so I will ask Ahmed to improve that, as I think it should not be too
difficult to achieve.

While many do not have PTP timing in their labs, it is becoming more and
more ubiquious so it is interesing when the entry level is so low. With
this little device you can do your normal TI-counter measurement even
for a PTP source. Exactly how much it filters, add noise and add time
bias, I do not know, yet.

I find it interesting that the PPS is such a common reference
measurement point, it keep showing up in packet timing solutions as a
reference point, including the ITU-T standards.

Cheers,
Magnus
