Hi, I found some documentation for the Timeprovider 4100 and there are 2 ports which can be configured to output either 1PPS or 10MHz. The latter is a square wave so I guess I can plug that into the Octoclock:
[image: image.png] The question now is if the Timeprovider's PPS output is compatible with the Octoclock. I note the pulse width is configurable is set to 1000, and there is also an offset param: [image: image.png] And, if the PPS is ok then can the Octoclock derive the Freq from that or is it better to plug both in separately.
