powervoltagedata acquisition

Overview
The Voyager M4120 provides engineers with lossless, end-to-end capture and visualization of USB4 120Gb/s Asymmetric Link and legacy USB traffic to speed validation and debugging. Capture USB4 and USB 3.2 with Power Delivery (EPR up to 50V), SBU/DP AUX and observe host, hub and device interactions.

• 120Gb/s USB4 Asymmetric Link capture and analysis
• Full USB4 v2 support plus Thunderbolt and legacy USB speeds
• Power Delivery (EPR up to 50V) monitoring and synchronized power graphs

Key Features

• Native USB Type‑C front-end ports for lossless capture of USB4 (Gen2/Gen3/Gen4), Thunderbolt, USB 3.2 and USB 2.0, plus Power Delivery (CC) and DP AUX (alt‑mode)
• Support for USB4 120Gb/s Asymmetric and Symmetric Gen4 (PAM3), Gen3, Gen2 and legacy lane rates (480Mb/s–120Gb/s)
• Visualization of Asymmetric Link operation with rapid identification of asymmetric configurations (e.g., 3Tx indicators)
• CATC Trace industry-standard display with packet labels, custom colors, expand/collapse transfer levels and packet filtering
• Tunneling support for native analysis of tunneled protocols and export to protocol suites
• Error detection and annotation across protocol layers (CRC, framing, timing)
• Power Tracker option for synchronized VBUS, CC and VCONN measurements

Flexible Hardware

• USB4-certified front-end connectors supporting full 80Gb/s per active link for lossless capture
• LED indicators for link speed, link width and active mode
• CATC Sync port for synchronized multi-box (cascaded) recording
• SuperSpeed 3.0 and Gigabit Ethernet host interfaces

Complete USB Test Coverage

• Captures USB4 Gen4 asymmetric 120Gb/s, USB4 Gen3x2 (40Gb/s), USB 3.2 Gen2x2 (20Gb/s), Gen2x1 (10Gb/s) and USB 2.0
• Supports Power Delivery including EPR up to 50V (with Power Tracker option)
• Trigger In/Out and advanced trace features for faster debug

Options and Extensions

• Asymmetric Mode Option — enables capture & analysis of USB4 Asymmetric Link configurations
• USB4 Exerciser Option — traffic generation for USB4 and Thunderbolt; transmit custom packets and emulate host/device/router operations
• DisplayPort Tunneling Exerciser (future option)
• Power Tracker Option — continuous sampling of VBUS/CC/VCONN with timeline graphs; required for PD Compliance Suite
• SimPASS USB — import and analyze simulation vectors for USB4 simulation files
• Gen T Exerciser Option — functional and compliance testing for Gen T

Error Detection & Power Measurement

• Protocol violation highlighting and annotations across layers
• Power Tracker displays synchronized power/current graphs with separate CC and VCONN plots and delta markers
