3. May 17, 20003 USB Bus Analyzers Brian Leete Intelbrian.a.leete@intel.com

4. May 17, 20004 Introduction w General Architectures w Predominate Features Available Today – With examples w Overall impressions of USB2.0 Test Tools w List of Players and Contact Info w Disclaimers

5. May 17, 20005 Dedicated Vs. General Purpose Solutions + Typically Simple HW Setup + Targeted Software + Single Vendor for all components – Economies of scale may not have kicked in – Not configurable beyond design specifications Dedicated Solutions

6. May 17, 20006 Dedicated Vs. General Purpose Solutions + Small Cost if you already have the Logic Analyzer + Over-design of Analyzer offset by Economies of Scale + You get to keep the Analyzer! + Logic Analyzer provides additional complex triggering capabilities + Tighter integration with other tools, other busses, Multiple USB’s. – Complexity General Purpose Solutions

7. May 17, 20007 Bus Analyzers by Architecture w Catalyst w CATC w Data Transit w Quality Logic Dedicated General Purpose w Crescent Heart Software (Tektronix) w FuturePlus (Agilent)
