Hi Magnus,
they did get the data from the scopes into NI Labview, not an easy task by  
With my HP 54720D scope I can get down to 200ps or so resolution, with  
about 60ps jitter from the scope, so for what they were trying to do a scope  
should be ok (getting around 1ns resolution I guess)..

That they didn't use a  time-interval counter but scopes kind of 
indicates that they may not have  been sufficiently equipped for this  task.
