The Beagle USB 480 Protocol Analyzer is a non-intrusive high-speed USB 2.0 bus monitor. Developers can see what is happening on the USB bus in real-time with 16.67ns resolution packet-level timing.
Features
Non-intrusively monitor High-speed USB 2.0 (up to 480 Mbps)
Two capture modes: real-time and delayed-download
High-speed USB chirp detection
Robust automatic speed detection
Hardware-based packet suppression
Digital inputs and outputs for synchronizing with external logic
Detect suspend/resume events and unexpected signals
Real-time capture and delayed-download capture
The Beagle USB 480 Protocol Analyzer has two different capture modes: real-time capture and delayed-download capture. The real-time capture mode allows developers to see all the high-speed data over USB as it happens. As the data is streamed in real-time, the capture size is only limited by the amount of RAM available on the analysis computer.
The delayed-download capture can be very useful in certain situations, such as when the Beagle USB 480 Protocol Analyzer is on the same high-speed bus as the target device. In these configurations, the Beagle analyzer is able to consume minimal USB bandwidth so that it does not obscure problems that occur only when the target is operating at the full USB bandwidth.
High-Speed USB Chirp Detection
The Beagle USB 480 Protocol Analyzer can capture and display the K and J chirp patterns used in high-speed speed negotiations.
Automatic Speed Detection
The Beagle USB 480 Protocol Analyzer is able to robustly and reliably detect the correct speed of the USB data it is monitoring.
Hardware-based packet suppression
A hardware input filter is available to suppress packets in order to reduce the amount of data captured. The filter can remove empty packet pairs such as IN/NAK and PING/NAK pairs.
Digital I/O for synchronizing
To assist in identifying problems, the Beagle USB 480 Protocol Analyzer provides four digital inputs that allows users to capture additional hardware events in-line with the captured USB data from the target device.
Four digital outputs are available to provide for synchronization of the Beagle analyzer with scopes and logic analyzers. These digital outputs are able to match patterns in the captured data as well as idle bus states.
Detect Bus Events and Unexpected Signals
The Beagle USB 480 Protocol Analyzer can intelligently detect suspend and resume events as well as unexpected signals on the bus.
