Signal analyzer Voyager M480x™

for electronicsfor testingvoltage

Overview
The Voyager M480x is an 80Gb/s USB4 protocol analyzer and optional exerciser platform that captures and generates USB4 (Gen 4 PAM3), Gen 3, Gen 2, legacy USB 3.2 and USB Power Delivery (including EPR up to 50V) traffic. It records side-band (SBU) traffic, Type-C signaling, and the full host/hub/device interaction, supporting Thunderbolt compatibility and tunnel export for deeper analysis.

Key Capabilities

• Capture and generation of USB4 80Gb/s Gen 4 (PAM3), Gen 3, Gen 2 and legacy USB 3.2 traffic
• Power Delivery (PD) capture and decoding, including PD handshake and EPR up to 50V
• Capture of SBU (side-band) and alt‑mode (e.g., DisplayPort) traffic
• Native USB Type‑C ports for loss‑less capture of all active links
• Optional exerciser for traffic generation (USB2.0, 3.2, USB4; Gen 4 exerciser mode available)

Recording and Capture

• Up to 32 GB recording memory for long trace capture
• HopID filtering to focus analysis on specific paths or functions
• Non‑intrusive probing to capture true power‑on link training and operation
• Trigger In/Out and synchronized multi‑box (CATC Sync) recording for cascaded systems

Flexible Hardware
The front‑end features USB4‑certified native Type‑C connectors supporting full 80Gb/s data rates for lossless capture. Front‑panel LEDs indicate link speed, width and active mode. Interfaces include SuperSpeed 3.0 and Gigabit Ethernet host connectivity.

Analysis Software & Decoding
The Voyager uses the CATC Trace viewer, providing a unified display with all packets labeled and interleaved for single‑view analysis. Features include:

• Full protocol decoding for USB4 logical links, PD and SBU register transactions
• Display of logical sub‑states (SLOS patterns, training sequences, DESKEW ordered sets)
• Grouping of register Read Request/Response for router enumeration debugging
• Expand/collapse transport layer for faster interpretation
• Export of tunneled USB4 traffic to PCIe, Video or USB Suites for detailed decoding of encapsulated protocols

Error Detection & Power Monitoring

• Automatic detection and labeling of USB4 link and protocol errors
• Low‑layer checks: training sequences, SCR content, CRC verification
• Logical layer checks: control packet timing and many USB4/USB3.2/PD logical checks (reserved fields, invalid frame sizes, correctable bit‑errors, etc.)
• Power Tracker option monitors VBUS, CC and VCONN voltages/currents graphically synchronized to trace events (required for PD Compliance Suite)

Exerciser & Options

• Exerciser option supports USB 2.0, USB 3.2 and USB4 traffic generation; low‑level control of headers, payloads, timing and link states; can emulate host or device router while recording DUT responses
• Gen T Exerciser option for Gen‑T testing (Part#: USB-AC60-V08-A) to support Gen‑T compliance test cases
• Gen 4 Exerciser Mode for USB4 80Gb/s validation: active Gen 4 traffic generation for corner‑case reproduction and link validation
• SimPASS USB supports pre‑silicon simulation file viewing and analysis, including USB4 40Gb/s and 80Gb/s simulation files
