Beagle™ USB Protocol Analyzer

Compatible Operating Systems: Windows 2000 SP4+, Windows XP SP2+, Linux (kernel 2.6+)

The Beagle™ USB Protocol Analyzer is a non-intrusive Full-/Low-Speed USB protocol analyzer. Developers can see what is happening on the USB bus in real-time with bit-level timing information at 21 ns resolution. Whether you are developing hardware, firmware, or software, the Beagle analyzer is an invaluable tool to help you see what is happening on the USB bus.

The Beagle USB Protocol Analyzer comes complete with the Beagle Data Center, a free software package for Windows and Linux. The Beagle Data Center allows developers to monitor and filter USB traffic in real-time. This software package is freely available for download on the Total Phase website, so you and your colleagues can share captured USB data.

Developers can also harness the power of the Beagle USB protocol analyzer in their own custom software thanks to the free and royalty-free Beagle API. All of the functionality of the Beagle analyzer is easily accessible for use in custom software for automated testing, production
line test fixtures, and much more.

Thanks to the Beagle analyzer’s low cost of $400, every engineer can have his or her own. That means you do not have to schedule time to share your analyzer with other developers. The bottom line is that your company saves time, effort, and money.
