1.2 Graphical Bus Traffic Display
The Advisor USB 2.0 Analyzer transaction displays use color and graphics to present the
captured transactions in an immediate, understandable and useful format.
Packets are shown on separate rows, with their individual fields both labeled and
color-coded. Packets are also numbered (sequentially, as recorded), time-stamped.
Protocol errors are automatically detected and highlighted in red.
The display is customizable, allowing the user to control the color scheme and the
formatting of field contents. A hide feature allowsusers to enable the suppression of SOF
packets and user defined packets or fields that may be uninteresting in a given context.
Display formats can be named and saved for later use. Pop-up tooltips annotate packet
fields with even more detailed information about their contents.
The display software operates independently of the hardware, allowing it to function as a
stand-alone Trace Viewer that is freely distributed.

1.3 Accurate Time Management
The Advisor USB2.0 Analyzer uses internal counter/timer circuitry to enable a reliable,
accurate (16.67 ns resolution) time stamping of recorded bus traffic. This timing
information is available both as a component of the graphical data display and as a
contribution to a variety of measurement and analysis functions. Any number of markers
can be added by the user to denote specific packets, and further timing measurements
can be made from one marker to another or from marker to trigger. All time fields are
presented as a time stamp, idle time, bit time or in a new time delta in either decimal or
hexadecimal format.
An essential feature of time management is that idle traffic does not consume the
Analyzer memory. Because of this unique technology, accurate timing calculations can
be made while still preserving valuable recording memory for important bus traffic.
1.4 Comprehensive Error Detection and Analysis
The Advisor USB2.0 Analyzer detects and alerts the user to every potential bus error,
protocol violation and/or combination thereof. The Analyzer contains circuitry in the
BusEngine™ to perform real-time triggering on multiple error conditions, such as PID
bad, bit stuffing bad, header or data CRC bad, end-of-packet bad, babble, loss of activity,
frame length violation, time-out or turn-around violation and data toggle violation. The
Analyzer program highlights all the hardware detected errors and further examines the
trace file for additional protocol errors, including wrong packet length, data payload
violation, and packet termination not on a byte boundary.
1.5 Real-Time Event Triggering and Capture Filtering
No attribute of a bus and protocol Analyzer is more important than its capacity for
extracting useful information from a crowded stream of bus traffic. The ability to
accurately identify, and selectively record, transactions of interest is the trait most
valuable to the user. The Advisor USB 2.0 Analyzer offers a unique approach to this
challenge. By using a set of recording resources, more than a dozen configurable
hardware building blocks can be optimized to perform a particular activity appropriate to
the task. A recording resource can independently await an initialization signal, monitor its
external environment (external signals, other resources) in search of a particular event
and take a subsequent action (triggering, inclusive or exclusive filtering, counting, etc.).
Under control of the user interface, these resources can be selected, configured and
combined to both search for complex trigger conditions and selectively capture the
associated transactions.
Thus, as well as triggering on basic events, such as specific bus conditions and packet
identifiers (PID) (see the Specifications section for a complete list), the Advisor USB2.0
Analyzercaneasilymanage the mostchallengingrequirements. Forexample:"triggeron
the fifth occurrence of a SETUP Token device number nine", or "trigger on a SET
INTERFACE request, following a specified eight-byte bulk data pattern match from this
scanner, and do not capture any start-of-frame (SOF) packets."
Theusercanalsoconfigurethesize of therecordingmemory,specifythepre/post-trigger
capture ratio, and truncate the capture of large data packets up to the first 256 bytes.

1.6 Advanced Event Counting and Sequencing
The count and sequence options define the rules for data recording sessions. These
options provide the ability to configure and control the order of events that have been
selected to trigger the USB2.0 Advisor Analyzer or filter the recording. There are two
counters and a restart option that causes the sequencing to start again.
By utilizing this feature a designer can specify a specific sequence of events that must
occur before the Analyzer triggers and finishes capturing data. This is extremely
important in allowing a designer to pinpoint certain types of events for recording. Without
this feature a designers must scroll through potentially megabytes of recorded data to
locate a specific sequence or occurrence of a sequence that can take hours to locate
before being able to begin analyzing the data of interest.
1.7 BusEngine Technology
LeCroy's BusEngine™ Technology is at the heart of the new Advisor USB 2.0 Analyzer.
The revolutionary BusEnginecore uses state-of-the-art Electrically Programmable Logic
Device (EPLD) technology and incorporates both the real-time recording engine and the
configurablebuildingblocksthatimplementdata/state/errordetection,triggering,capture
filtering, external signal monitoring and event counting & sequencing. And like the
flash-memory-based firmware that controls its operation, all BusEngine logic is fully field
upgradeable, using configuration files.

2.1 General Description
The LeCroy USB Advisor™ USB2.0 Protocol Analyzer is a stand-alone unit that is
designed to be controlled and configured by a portable or desktop PC connected via its
USB port.
The Advisor uses hardware triggering to capture real-time events and hardware filtering
to preserve memory and assist in pinpointing data of interest. Recorded data is then
uploaded to the attached PC and displayed on the CATC Trace graphical user interface
as color-coded packets that can be searched for specific data, errors or other desired
conditions.
The Advisor USB2.0 Bus & Protocol Analyzer is the ideal USB tool used in conjunction
with any Microsoft®Windows®2000, Windows XP, Windows Vista™ 32, or
Windows Vista 64 desktop or portable PC in a USB development lab environment.
Note: Support for Windows 2000 will end on January 1, 2008.
The Advisor Analyzer supports the Universal Serial Bus, version 2.0.
Please refer to the Universal Serial Bus Specification, version 2.0 for details on the
protocol. The USB specification is available from the USB Implementers Forum (USB-IF)

2.2 Analyzer PC Requirements
The following is a list of recommended configuration for the host machine that runs the
Advisor application and that is connected to the Advisor 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 Advisor 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 AMD Athlon/Duron family, or other compatible processors with clock speed of
500 mHz or higher. (A processor of the Intel Pentium II/Celeron family or
AMD K6 family with clock speed of 300mHz is required.)
• For the best performance, it is recommendedto have physical RAM twice the size of
the recording buffer setup - 256 MB or more. (Minimum is 128 MB of RAM.)
• At least 20 MB of free hard disk space is required for the installation. Additional disk
space is needed for storing the recorded data in files during the recordings process
(can be as much as 150MB when recording a full buffer size).
• Display: Resolution of 1024 x 768 with at least 16-bit color is recommended (resolu-
tion of 800 × 600 with 16-bit color is a minimum).
• A USB interface is required to connect to the Advisor Analyzer. This is not a require-
ment if the application is going to be used only as a viewer.
2.3 System Components/Packing List
The LeCroy Advisor Analyzer package includes the following items:
• One stand-alone LeCroy USB Advisor™ Analyzer module
• One AC power cord with a plug appropriate to your location
