7 5/27/2008 LXI IntroductionPage 14tmLXI summary LXI is LAN done well with an open industry standardthat can coexist with GPIB, PXI and VXI. LXI is easy to adopt and an increasing percentage of rack & stack instruments conform to LXI Class C. Class B will become increasing common and will likely be the new baseline over time. LXI can simplify ATE integrationand provides time synchronization, triggering, and peer-to-peer communication capabilities that can reduce or eliminate the need for high-speed backplanes / card cages.

8 Long-term support and backward compatibility of LANmakes LXI an excellent choice for the defense industry. LXI can improve important ATE / DUT interaction such as speeding up emergency shutdowns to help prevent damage to expensive hardware. LXI instrument can help facilitate other important test equipment related functions (calibration due dates, asset utilization rates, etc.) 5/27/2008 LXI IntroductionPage 15tmLXI Day AgendaLunch
