Description
The Beagle USB 12 is a full/low-speed, distortion-free USB protocol analyzer. Developers can monitor traffic on the bus. This with a bit-level timing information resolution of 21 ns.
Hardware requirement
- Intel or AMD 2 GHz processor or faster
- 1 gigabyte (GB) of physical RAM (32-bit) or 2 GB of RAM (64-bit)
- 2 GB or more available disk space
- High Speed USB Port
- VGA suitable for a screen resolution of 1024 x 768 or higher
- Internet access is helpful

Supported operating systems (32-bit and 64-bit)
- Windows: 7, 8, 8.1, 10
- Linux: Red Hat, SuSE, Ubuntu, Fedora, Arch, CentOS, Debian
- Mac OS X: 10.5-10.10

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. As a high-speed device, all data collected by the Beagle USB 12 analyzer is transmitted to the test computer at 480 Mbit/s. As a low-power device, the Beagle USB 12 Analyzer does not require a power adapter. This makes the Beagle USB 12 Analyzer the ideal tool for engineers in the field. Just plug it into a high-speed USB 2.0 port on your laptop.
Cost-efficient and future-proof
The Beagle USB 12 Protocol Analyzer comes complete with the software.The low cost allows companies to provide each developer with their own analyzer, making it quick and easy to identify and fix problems. Less time spent means more productivity, projects are completed on time and on budget.
The Beagle USB 12 is regularly supplied with updates via USB.
New software functions are always available promptly and can be downloaded free of charge
Available software

Data Center
Data Center™ software is free bus monitor software that captures and displays USB, USB Type-C Power Delivery, I2C, SPI, eSPI and CAN bus data via the hardware protocols. Data Center is the only protocol analysis software with real-time performance and cross-platform support for Windows, Linux and Mac OS X.

Labview Driver
The Beagle LabVIEW driver is a free open source LabVIEW instrument driver for accessing the Beagle protocol analyzers within the LabVIEW development environment. The driver package is targeted at Windows and is based on the Beagle software library.

API's
The Beagle USB 480 Protocol Analyzer has a comprehensive API for Rosetta language bindings - 32-bit and 64-bit software API C, C#, Python 2/3, .NET, VB.NET and VB6. The Labview drivers provide all the functionality normally available to a C language developer. Windows 10, 11, Max OS X 10 - 11, Ubunto, Fedora, SuSE and Red Hat are supported.
