Beagle USB 480 Power Protocol Analyzer

The Total Phase Beagle USB 480 Power Protocol Analyzer is a non-intrusive USB 2.0 analyzer that captures Low, Full and High-Speed USB 2.0 traffic (up to 480 Mbps) while simultaneously graphing VBus current and voltage in real time. By interleaving power readings with the packet stream, it lets engineers correlate power behaviour with specific USB transactions, capturing inrush current, suspend/resume power profiles and charging negotiation directly against the protocol timeline. Peak measurement capacity is 20 V and 3 A (transient), with packet-level timing at 16.67 ns resolution.

The analyzer ships in two editions. The Standard Edition provides a 64 MB hardware buffer with full VBus current/voltage graphing. The Ultimate Edition adds a 256 MB buffer, USB 2.0 advanced triggering, hardware packet filtering and one-click power-to-protocol correlation (detailed below).

A USB power delivery analyzer: link VBus current and voltage with USB data

Few tools dedicated to measuring USB VBus current and voltage also link those measurements back to the captured USB data. The Beagle USB 480 Power does exactly that: it graphs VBus current and voltage values in real time inside the Data Center Software and aligns them with the USB packet stream. Engineers building host-side products such as rechargeable batteries, tablets and laptops can verify VBus current/voltage output and observe the effect of attaching peripherals; engineers building peripherals such as cameras, HID devices, mobile devices and portable mass storage can verify exactly how much current and voltage their device consumes with respect to timing and USB data. This makes it well suited to USB charging and USB power delivery debugging where power and protocol behaviour must be understood together.

Real-time, non-intrusive USB 2.0 monitoring

The analyzer is a passive bus tap: it performs real-time data analysis and display without altering signalling on the link under test. Digital inputs and outputs on the Mini-DIN 9 connector synchronise captures with oscilloscopes or logic analyzers. A royalty-free Beagle API (C/C++/C#, Python, .NET, VB.NET, Visual Basic 6) supports integration into automated USB test setups.

Real-time USB class-level decoding

Through the Data Center Software, the Beagle USB 480 Power performs real-time USB class-level decoding for HID, Audio, Video, Still Image, Printer, Mass Storage, Hub, Network, Mobile and CDC classes. LiveDisplay technology shows current/voltage readings and USB traffic as they are captured, and LiveFilter and LiveSearch allow interactive filtering and searching during analysis.

Ultimate Edition: 256 MB buffer and USB 2.0 advanced triggering

The following are Ultimate-Edition capabilities (the Standard Edition has a 64 MB buffer and VBus graphing without the advanced trigger engine):

The advanced state-based trigger engine lets developers trigger the capture, assert external outputs, filter matching data or move to another state based on data patterns, packet types, error types, events and other criteria. These advanced triggers come standard on the Ultimate Edition and can also be added to a Standard Edition unit as a separate USB 2.0 Advanced Triggers license upgrade.

Applications

• USB charging and power delivery verification: capture inrush current, charging negotiation and VBus behaviour against the protocol timeline.
• Battery-powered and portable device development: profile suspend/resume power on wearables, handheld instruments and IoT hardware.
• USB peripheral power profiling: measure current and voltage consumed by cameras, HID, mobile and mass-storage devices with respect to USB timing.
• Host-side product validation: verify VBus output on tablets, laptops and battery packs under varying peripheral loads.
• Automated USB compliance and regression testing: integrate capture and trigger control through the Beagle API.
