Wireless USB tools to address ultra-wideband development, test

Supporting certified WUSB (Wireless Universal Serial Bus) and WiMedia UWB interface standards, new protocol analysis and traffic-generation tools soon to be released from LeCroy Corp promise to provide insight at each stage of a product's development lifecycle. These tools come just as the WUSB v1.0 spec has been published.

Targeting new serial data testing, LeCroy's UWBTracer system will be a protocol analyzer for radio-based traffic using the WiMedia Alliance's UWB (Ultra Wideband) common radio platform and WUSB from the USB-IF standards.

Additionally, LeCroy will also be rolling out a UWBTrainer traffic generation system. Current LeCroy USB test equipment users will also be able to upgrade the capabilities of their USB protocol analyzers to include wire-line adapter decode support.

The pre-announcement of these products comes after the successful introduction of the company's first UWB protocol analyzer, the UWBTracer MPI. It's used during early stages of UWB development while integrating MAC (Media Access Control) and PHY (physical layer) chipsets.

CATC roots

The UWBTracer protocol analyzer was developed by LeCroy's Protocol Solutions Group. It was formerly a company called CATC (Computer Access Technology Corp.) until LeCroy acquired it. CATC specialized in USB and Bluetooth and Fiber Channel protocol analysis tools. CATC was the first company to introduce commercially available USB and Bluetooth protocol test equipment.

LeCroy's CATC-derived UWBTracer is capable of capturing and decoding WiMedia and Certified Wireless USB traffic exchanged over the air. The system also provides capture and analysis of MAC and PHY interface traffic between modules or chipsets.

The combination of radio-based analysis, as well as MPI recording, will make the UWBTracer analyzer useful at every stage of product development. Beginning with the initial debug of a MAC PHY communication path, to eventual interoperability testing between different WiMedia-based devices, LeCroy says its UWBTracer analyzer is designed to reduce time-to-market for Certified WUSB chipsets, devices, and software. It will also include support for multiple association models as well as encryption.

The UWBTracer will feature CATC Trace software. It logically organizes and displays the protocol hierarchically, all the way from WiMedia-based frames up to WUSB transfer. The analysis and control software, now a de facto industry standard, includes powerful triggering and filtering, and pop-up tool tips that explain the protocol in context of the captured traffic.

Additionally, you will be able to isolate specific MPI and WUSB events using a search function. Realtime statistics will provide additional insight into operation and performance.

The UWBTracer analyzer will begin shipping in the first quarter of 2006, with the UWBTrainer traffic generator following soon after. Wire Line Adapter Decode support for USB will become available in this quarter.
