Teledyne LeCroy USB protocol analyzers connect to portable or desktop host machines. Analyzers are configured and controlled by USB Protocol Suite software, which installs onto host machines running 64-bit versions of Microsoft Windows Server 2019, Windows Server 2016, Windows 11, or Windows 10.
Analyzers provide traffic capture and analysis. Hardware triggering allows capture of real-time events. Hardware filtering allows filtering different packet types in or out of the recording (see Real-Time Event Triggering and Capture Filtering). Filtering also allows you to preserve recording memory, for extended recording time.
The trace viewer application (see Graphical Bus Traffic Display) displays recorded data in colored graphics. The application has advanced search and viewing capabilities that allow you to quickly locate specific data, errors, and other conditions.
The system provides on-the-fly detection of, and triggering on, events like Tokens and Errors (see Comprehensive Error Detection and Analysis). Whether recording manually or with a specified trigger condition, the system continuously records the link data, in a wraparound fashion, until manually stopped or until the system detects the Trigger Event and records the specified post-trigger amount of link data.
Upon detection of a triggering event, the analyzer continues to record data up to a point specified by you. You can individually enable or disable real-time event detection to allow triggering on events as they happen, including predefined exception or error conditions and user-defined sets of trigger events. An externally supplied signal can trigger the analyzer. You can search to investigate events. In addition to immediate analysis, you can print any part of the data. You can save the data on disk for later viewing. You can generate timing information and data analysis reports.
Note: Voyager M4120, M480x, and M4x analyzers support both USB4 and Thunderbolt 3 (TBT3) capture and analysis. The term USB4 is used throughout this manual to denote the features involving capturing both USB4 traffic and legacy TBT3 traffic. Where differences exist, a note will provide explanation.
