Hi Marcello,

The problem with a storage scope is finding ways of triggering the thing so  
it shows what you are looking for.  The proposed new scope should be up to  
the job, as the minimum timebase sweep duration gives 50 nsec per division it  
seems.  This should show events down to 10 nsec, bearing in mind the  bandwidth 
limitation.  

Getting it to look for the event you wish to capture **at the time it is  
happening** is the real challenge!  When I was working as an engineer, we  would 
sometimes write code routines to do a certain step repetitively to catch  
those events, but this is a much more practical proposition if you have an  
E(E)PROM emulator, a very desirable tool.  Much cheaper than a logic  analyser too.  
Good hunting!
