Non-intrusive USB monitoring

The Beagle USB 12 Analyzer is galvanically isolated so it does not affect the system under test and does not falsify the results. Simply plug the Beagle USB 12 inline to passively monitor full-speed and low-speed USB devices. It is also possible to monitor high-speed devices by connecting the device through a full-speed hub.

USB Descriptor Decode

The Data Center Software's class-level decoding feature enables real-time decoding of USB descriptors for data captured with a Beagle USB 12 Protocol Analyzer. Full class-level decoding is available with the Beagle USB 480 Protocol Analyzer.

Real time display & Unlimited data collection 

With the Beagle USB 12 Protocol Analyzer you can see the USB packets in real time as they are sent over the USB bus.
The captured data is transmitted directly to your computer via high-speed USB. The amount of data collected is only limited by the physical memory available on the device.

High Speed ​​USB 2.0>

The Beagle USB 12 Analyzer is a high-speed, bus-powered USB 2.0 device. This offers two main advantages.
