Teledyne LeCroy Voyager M3x Protocol Analyzer

The Teledyne LeCroy Voyager M3x is a 7th-generation USB protocol analyzer that captures, analyzes, and debugs USB traffic across multiple protocol layers with real-time visibility and hardware-level precision. It supports USB 2.0 (Low-Speed, Full-Speed, High-Speed) and USB 3.0/3.1/3.2 Gen 1 SuperSpeed at 5 Gbps, operating simultaneously on both buses for end-to-end validation across hubs and complex topologies. The instrument combines a full-featured protocol analyzer with an integrated exerciser for custom traffic generation and compliance testing.

– Technical Specifications

• Concurrent Capture: USB 2.0 and USB 3.0 traffic simultaneously
• Recording Memory: 4 GB onboard; spool-to-disk support for extended sessions
• Timing Resolution: 2 ns (Link Tracker View)
• Error Detection: 10-bit error detection with logical link and timing error flagging
• Protocols: USB 2.0 (LS/FS/HS), USB 3.0/3.1/3.2 Gen 1 (5 Gbps SuperSpeed)

– Key Features

• Real-time traffic filtering discards redundant patterns (SKPs, idles, LFPS, training sequences) to optimize buffer and debugging efficiency
• Link Tracker View captures every transition with 2 ns timing resolution, displaying raw 10-bit data patterns and ordered sets in multiple Hex formats
• 10-bit symbol correlation to higher-level packet structures enables root-cause analysis at every protocol layer
• Hardware triggering pinpoints specific protocol events without manual post-processing
• Full USB device class decoding supports Bulk Only Transport, USB Attached SCSI (UAS) with command queuing, and vendor-specific implementations
• Integrated exerciser emulates USB 2.0 and USB 3.0 hosts and devices with custom packet transmission, low-level header/payload control, and error injection
• USBTrainer 2.0 script backward compatibility for existing traffic generation workflows

– Typical Applications

• USB device and system development validation
• Protocol compliance and error injection testing
• Multi-layer debugging of complex USB hub and peripheral interactions
• Custom traffic generation for stress testing and edge-case validation

– Compatibility & Integration

Works with CATC Trace Analysis Software for advanced traffic analysis and reporting.
