also needed. This would normally be a 1 PPS signal generated by the
same
reference. It will need to go through some sort of active splitter and

Matt,

If the 1 pps signal were a square wave, pulse width 200 ms, with an
accuracy of ±130 ns with respect to UTC, would that work with the
current firmware installed in the U2?

Also, might an coax F-type active splitter (prob. intended for TV)
work? Or is there an active splitter you can suggest that would work
for sure?

Thanks,

You can use a splitter on the 10 MHz reference, but I wouldn’t suggest
using one on the PPS, since that is a digital signal that needs to be
more than the threshold voltage. A BNC Tee would probably work better.
