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,
Kyle
