Total Phase Beagle USB 12: USB 1.1 protocol analyzer, 12 Mbit/s

Description

The Total Phase Beagle USB 12 Protocol Analyzer (ref. TP320221) is a non-intrusive USB protocol analyzer for Full Speed and Low Speedlinks. It shows what happens on the USB bus as it happens, with 21 ns resolution and real-time USB descriptor decoding.

It sits between the host and the device under study, and a third port connects it to your analysis computer. Captured data is streamed continuously to the computer over high-speed USB, allowing captures of nearly unlimited duration, with traces of more than 25 GB.

This analyzer suits devices running up to 12 Mbit/s. It does not follow High Speed or SuperSpeed traffic: for those rates, Total Phase offers the Beagle USB 480 and Beagle USB 5000 v2.

Highlights

• Non-intrusive: monitoring of USB Full Speed (12 Mbit/s) and Low Speed (1.5 Mbit/s).
• Real time: live display of USB packets and USB-specific error codes.
• Decoding: USB descriptors decoded by the Data Center software.
• Large captures: traces of more than 25 GB, streamed continuously to the computer.
• Practical: powered by the USB 2.0 bus, no AC adapter needed.
• Free software and API.

Why a hardware analyzer? A software capture on the host, with usbmon or Wireshark, shows transfers as seen by the host's USB stack. The analyzer placed between the host and the device sees packets as they pass on the bus, without going through the driver you may be trying to investigate.

Beagle USB 12, USB 480 or USB 5000 v2: which should you choose?

Start from your device's actual speed, then the level of debugging you need.
