Overview

The Ellisys USB Explorer 260 is a sophisticated protocol test system for USB traffic monitoring, driver and software stack debugging, protocol compliance verification and performance analysis. The EX260 can reduce your R&D development time by finding issues early and debugging more efficiently, and can improve quality and reliability by verifying compliance to the specifications.

The multifunction USB Explorer 260 can:

• analyze USB 1.1 and USB 2.0 links at any speed, including OTG and the new InterChip-USB at all speeds and all voltages;
• emulate USB hosts and devices;
• inject pre-defined error patterns for stress and error recovery testing; and,
• automatically verify compliance to the USB and class specifications.

Each flexible Ellisys USB Explorer 260 hardware unit is capable of acting either as a protocol analyzer or a packet generator depending on configuration.

Analyzer Applications

• USB host and device traffic monitoring
• Drivers and software stacks debugging
• Passive protocol compliance verification
• Performance analysis

Analyzer Features

• Analyses links non-intrusively
• Transfers analyzed data in real-time for virtually unlimited recording time
• Highlights protocol errors and interoperability issues
• Efficiently decodes all requests and data structures

Typical Analysis Setup

The USB Explorer 260 Analyzer is connected in pass-through mode and records any traffic exchanged between a USB host and device. The host can be a PC, an embedded host or a USB Explorer 260 Generator.

Ellisys USB Explorer 260 Generator

Generator Applications

• USB host and device traffic emulation
• Error recovery mechanisms testing
• Active protocol compliance verification
• Stress testing

Generator Features

• Generates arbitrary packets with precise timing control
• Injects errors to test error recovery mechanisms
• Uses exported scripts from analyzer to play back all kind of scenarios
• Powerful scripting environment with integrated editor and debugger

Inline Error Injection Setup

A USB Explorer 260 Generator and USB Explorer 260 Analyzer are connected in pass-through mode between a USB host and device. The generator injects programmed errors on the link while the analyzer non-intrusively records any traffic exchanged between the host and the device.
