USB Explorer 260 Protocol Analyzer

Multifunction USB 2.0 Test System


USB Explorer 260
Multifunction USB 2.0 Protocol Test System

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.

  • 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.

The Ellisys USB Explorer 260 Analyzer includes Ellisys' extensive analysis features with real-time monitoring, hard-disk data streaming, in-depth class decoding, comprehensive traffic statistics, and powerful triggering and filtering.

The USB Explorer 260 Analyzer is based on Ellisys' renown USB analysis software that is well-proven for validating device enumeration, solving communication issues, detecting interoperability problems and optimizing performance.

The Ellisys USB Explorer 260 Generator complements protocol analysis by emulating USB devices and hosts, and by testing corner cases and recovery mechanisms. Reproducible traffic, timing and error scenarios can be created with a powerful scripting environment. Captured traffic can be replayed to test a particular situation. The Generator supports the industry's first Inline Error Injection feature to insert programmed errors between a host and device to determine the impact of transmission errors under rare conditions.

The Generator also includes the Ellisys USB Device Examiner Automated Pre-Compliance Testing software. This software controls a generator and an optional analyzer to automatically verify the compliance of devices against the USB specification and classes specifications such as HID and Mass Storage.




The Ellisys USB Explorer 260 Duo is a flexible bundle of two full-featured units that can be used as one analyzer and one generator, two analyzers or two generators depending on your testing requirements. More convenient than having both functions on the same unit, this allows you to better share your test equipment among your R&D team.


Typical Setup

USB Explorer 260 Analyzer
Analyzer Applications
  • USB host and device traffic monitoring
  • Drivers and software stacks debugging
  • Performance analysis
  • Passive protocol compliance verification
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.


Typical Generator Setup

USB Explorer 260 Generator
Generator Applications
  • USB host and device emulation
  • Error recovery mechanisms testing
  • Active protocol compliance verification
  • Stress testing
Generator Features
  • Generation of arbitrary packets with precise timing
  • Error injection capabilities to test 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

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.

The Ellisys USB Analyzer Software is available for download for evaluation. Many traces of various devices are included in the installation package to show the extensive class decoding of the software.


Explorer 260 Generator Software

The Ellisys USB Generator software is available for download for evaluation. Many sample scripts are included in the installation package to demonstrate the features of the generator.


Explorer 260 Device Examiner Software

The Ellisys USB Device Examiner (DEX) is a stand-alone USB device compliance test application that operates on the USB Explorer 260 hardware. DEX is provided with the Generator, or can be
added as an option to the Analyzer. DEX provides a comprehensive set of robust compliance tests covering Chapter 9 of the USB Specification (Device Framework).
