LeCroy Adds Timing Analysis Displays to UWBTracer Test and Verification Platform


October 1, 2007 , Certified Wireless USB Developers Conference, Amsterdam, the Netherlands: LeCroy Corporation, a worldwide leader for serial data test announced it has released several new graphical displays to help users optimize performance and debug protocol issues for WiMedia and Wireless USB. Part of the UWBTracer/Trainer version 3.0 software suite, LeCroy's newest release helps users boost Wireless USB channel efficiency by making it easy to identify marginal timing conditions that may impact performance.

The all new Wireless USB View presents logical USB transactions overlaid with the actual Wireless USB packets recorded by the analyzer. Timing measurements are possible by clicking and dragging the cursors to show packet-to-packet or MMC-to-expected MMC time deltas.

"The ability to identify even small timing issues is essential for performance tuning, and allows us to reduce inefficiencies between the Wireless USB host and device" said Randy Erman, UWB Software Manager at Stonestreet One. "LeCroy's Wireless USB View maps the logical channel time to actual packets transmitted over-the-air. This helps us to identify any underlying problems at the wireless USB handshake and Device Reservation Protocol (DRP) layers."

Fully customizable, the new Beacon Period View shows slot occupancy information using colors and graphics to help users understand beacon status at a glance. It presents a scrollable time line where multiple beacon periods can be viewed in a single screen. The display preserves historical beacon slot information for the previous four superframes allowing users to identify possible protocol violations.

LeCroy recently released the UWB Trainer which adds an advanced exerciser option to the UWB analyzer platform. While the exerciser transmits packets, LeCroy's UWB analyzer operates continuously to record the wireless traffic from WiMedia devices while presenting the exchange using the defacto standard CATC Trace display. The new timing analysis views are available free of charge to registered users of the LeCroy UWB analyzer Download version 3.0 on the LeCroy download page: www.lecroy.com/tm/Library/Software/PSG/tracersw.asp?menuid=8
