No problem, happens to me too some times,
 
usually the 10MHz Sine should be loaded with 50 Ohms, and the CMOS/TTL 1PPS 
 pulses should be run open-ended (1M or higher)..
 
I say usually.. because there are cases where proper termination is  
critical such as LVDS 1PPS outputs.. and where the 10MHz does not necessarily  
need to be loaded with 50 Ohms, resulting in a higher sine wave voltage - such  
as on our JLT GPSDO products..
 
bye,
Said

I guess  this it what they would call a rookie move? WOW, i feel like an
idiot. I  just loaded it down with a 50 ohm load and looks perfect. Thanks
for  enlightening  me.
