LXI Trigger Bus

 Tight synchronization of

Data

 Easier to define

events

 Analysis has become

more dependent on time stamp

 Several units can be

daisy chained

 More channels for high

sample rates

User Interface

 UI must be intuitive!

 Minimizes training of personnel  Reduces error when operating equipment  Setup and data reduction will not consume time

 Allows us flexibility to change UI  Removes possibilities of licensing issues  Continued use of Legacy equipment
