Beagle USB 12 Protocol Analyzer – TP320221
Watch Full-speed and Low-speed USB traffic as it happens
The Beagle USB 12 sits in line between a USB host and a USB device and records the traffic between them without taking part in it. It covers Full-speed (12 Mbps) and Low-speed (1.5 Mbps) USB, parses descriptors live and time-stamps events to 21 ns.
The capture streams to the PC, so a trace can grow past 25 GB. The analyzer takes its power from the USB analysis port and needs no external supply.
