Chapter 1: Overview
The LeCroy USBMobileHS™ USB Hi-Speed Analyzer is a portable, PC Card based, bus
and protocol analyzer that accurately and efficiently debugs, tests and verifies Low, Full,
and Hi-Speed USB semiconductors, devices, software and systems. USBMobileHS
features the CATC Trace software, the de facto standard for recording and analyzing
USB protocol traffic. The CATC Trace simplifies the overall debug process by using
collapsible,color-codedschemesto representthe USBPacket,TransferandTransaction
layers.Itsnative On-The-Go(OTG)supportautomaticallydetects,decodes,anddisplays
the HNP and SRP protocols, including VBus pulsing. The USBMobileHS builds upon
LeCroy's experience and knowledge of the needs of the USB development and test
communities. The result is a USB bus and protocol analyzer with unprecedented
functionality, unparalleled flexibility, and uncompromising user friendliness.

1.1 Event Triggering
For efficient development of USB systems, it is critical that users are able to extract
important information from a crowded stream of bus traffic, and accurately identify and
selectively record information that is of most interest. The Events and Action fields for
trigger set-up is intuitive and graphical, thus making pre-recording set-up time efficient.
USBMobileHS provides real-time hardware triggering on the critical components of USB.
Userscancustom-configureandcontrolorderofeventsselectedfor triggering.The count
and sequence options define the rules for data recording sessions. There are two
Counters, Filter Out/In and a Restart option that causes sequencing and counting to start
again. Any sequence can include up to seven events of any type.
Users can adjust the depth of the recording memory - up to 64 megabytes - and
determine where in the recording the trigger is located.

1.2 On The Go Support
The USBMobileHS supports OTG (On-The-Go) capabilities. OTG is an emerging
standard in the USB specifications that allows peer-to-peer connectivity among USB
devices and provides a standard USB connection among portable devices. The Analyzer
identifies both the HNP (Host Negotiation Protocol) and SRP (Session Request Protocol)
occurrences, searches for Host A or B, and identifies timing anomalies during HNP and
SRP protocols.

1.3 The CATC Trace
The CATC Trace's ability to extract critical information quickly and intuitively from a
crowded stream of bus traffic is unparalleled. The ability to accurately identify and isolate
very specific packets is vital to speeding debug and development time. Powerful Search
and Find options allow users to quickly get to specific packets, errors and any data type
within a trace file. With filter and hide commands, the CATC Trace removes irrelevant
data from the Trace for efficient viewing.

USBMobileHS provides on-the-fly detection of and triggering on such events as specific
user-defined bus conditions, packets matching any Packet Identifier (PID), packets
matching a Token or Setup transaction, data patterns, and errors and bus conditions.
Whether recording manually or with a specified Trigger condition, USBMobileHS
continuously records the bus data in a wrap-around fashion until manually stopped or
until the Trigger Event is detected and a specified post-Trigger amount of bus data is
recorded.
Upon detection of a triggering event, the Analyzer continues to record data up to a point
specified by the user. Real-time detection of events can be individually enabled or
disabled toallow triggering oneventsas theyhappen.Thisincludes predefinedexception
or error conditions and a user-defined set of Trigger events.
TheUSBMobileHS softwareprovides powerful search functions thatenableinvestigation
of particular bus events and allow the software to identify and highlight specific events.
In addition to immediate analysis, you can print any part of the data. Use the Save As
feature to save the data on disk for later viewing. The program also provides a variety of
timing information and data analysis reports.
2.3 Analyzer PC Requirements
The following is a list of recommended configuration for the host machine that runs the
USBMobileHS application and that is connected to the USBMobileHS Analyzer:
•Microsoft
®Windows®2000, Windows XP, Windows Vista™ 32, or
Windows Vista 64 operating system. Note: Support for Windows 2000 will
end on January 1, 2008. The USBMobileHS application can be used on
machines with Windows to view trace files. Microsoft Internet Explorer,
version 5 or newer.
• For optimum performance, use processors of the Intel Pentium III/Pentium 4
family or the AMD Athlon/Duron family, or other compatible processors with
clock speed of 500mHz or higher (Processors of the Intel Pentium II/Celeron
family or AMD K6 family with clock speed of 300mHz or higher are required.)
• For the best performance, it is recommended to have a minimum of 128 MB
of RAM.
• At least 20 MB of free hard disk space is required for the USBMobileHS
installation. Additional disk space is needed for storing the recorded data in
files during the recordings process (canbe as much as 50 MB when recording
a full buffer size).
• Display: Resolution of 1024 x 768 with at least 16-bit color is recommended.
(Resolution of 800 × 600 with 16-bit color is required.)

Chapter 3: Installation
3.1 USB Test Ports
Connect a host to one of the mini A-B receptacles (use an adaptor if necessary), and
connect your device to the other. It does not matter which receptacle you plug into.
Note: TheUSBMobileHS USB 2.0Classic Analyzeris nota hubdevice; it connects
to a USB branch by inserting a non-intrusive, high impedance tap. Because
of the poor signal quality in the middle of a USB cable, LeCroy recommends
using the shortest possible cables so that the total length of both cables
together is less than 6 feet. The USB cables provided with your Analyzer
meet this requirement. When longer cables are used, the Analyzer might
record incorrect data.
3.2 Software Installation
Step 1 Insert the USBMobileHS CD-ROM into your computer.
Step 2 Click Install Software when the Auto-Run program is displayed.
Step 3 Follow the installation instructions on your screen.
The Install Wizard automatically installs the necessary files to the computer’s hard drive.
The software is installed in the C:\Program Files\LeCroy\USBMobileHS directory
