Part No:MPELLI-USBAL-USB-Exp280
The
USB Explorer 280 is a sophisticated protocol test and
analysis system for USB Super Speed traffic monitoring, driver and
software stack debugging, and performance analysis. The USB Explorer 280
is designed to reduce R&D time by finding issues early and debugging
more efficiently, and can improve quality and reliability by verifying
adherence to the specification.
The
multifunction USB Explorer 280 can:
- Analyze USB 3.0 (Super Speed) and USB 2.0
links (High Speed, Full Speed, Low Speed)
- Emulate USB hosts and devices
- Automatically detect link speed and SS
receivers
- Upload and display live data during
recording
- Record LFPS states and display state
transitions
- Connect to differential SMA for alternative
front-end probing during prototype stages
The USB Explorer 280 builds on a successful
legacy of USB analyzer and generator products, and delivers a superior
design efficiency that includes an embedded 4GB of memory,
configuration-flexible hardware, and a custom-made processor with the
power needed to test and analyze the USB 3.0 5GT/s Super Speed mode.
Each USB Explorer 280 hardware unit is capable
of acting as either a protocol analyzer or packet generator, depending
on the configuration.
Configurations
The USB Explorer 280 Analyzer
includes extensive protocol analysis features, including real-time
monitoring and live upload of captured traffic, detailed decoding of
standard and class requests, trigger, filter, and search functions, and
comprehensive statistical analyses. Automated support for spread
spectrum clocking (SSC), data scrambling, and receiver equalization
techniques is included.
The USB Explorer 280 Analyzer is based on the
intuitive Visual USB™ software application that is well-proven for
performance optimization and validation of device enumeration, bus
operation, and interoperability testing. New analysis features designed
specifically for USB Super Speed have been added to provide the user
with a comprehensive analysis solution ideal for any USB design effort.
The USB Explorer 280 Generator
supplements protocol analysis by emulating USB hosts and devices. The
USB Explorer 280 Generator is ideal for testing corner cases, error
recovery protocols, link power state transitions, and link training
issues. The Generator includes a low-level, powerful scripting interface
favored by engineers looking to control protocol sequences and responses
at precise timing granularities.
The USB Explorer 280 Duo is a
highly flexible bundle of two full-featured units that can be used as
one analyzer and one generator, two analyzers, or two generators,
depending on the needs of the user. Even more convenient that simply
having these two functions on a single hardware unit, this innovative
and flexible architecture allows engineers to share units among the R&D
team.
Analyzer Applications
- USB host and device traffic monitoring
- Drivers and software stacks debugging
- Performance analysis
- Link state analysis
Analyzer Features
- Automatic detection of link speed
- Automatic detection of SS receivers
- Hardware triggering and filtering
- Instant Timing™ view for graphical,
intuitive understanding of bi-directional traffic elements and
critical timing measurements
Typical Analysis Setup
The USB Explorer 280 is connected in a logically
passive mode to record traffic and bus events passing between host and
device. The analyzer provides same-link concurrent support for USB 3.0
and USB 2.0 speeds, which is especially valuable for development of hubs
supporting USB 3.0 and USB 2.0 specifications.
