Hi all,

I'm currently trying to build events through doing block transfers. The worry was 
that organizing and packaging bank data into an array would produce too much dead 
time causing too many missed events. Trying out that method, I'm running into all 
sorts of issues such as unaligned transfers where the QDC events are unaligned, or 
improperly aligned banks. Giving me a headache.

My question is, if I were to revert back to simple 32 bit read cycles and using 
the fevme.cxx template's method of organizing data before sending them to the 
buffer, what kind of deadtime should I expect? Am I wrong to assume that this 
would result in deadtime at all? I'm using a CAEN V792n 16 channel QDC and the hit 
frequency that I'm using to test is 20kHz.

Thanks.

Isaac
