Chapter 1: Overview
1.1 Common Features
1.1.1 Graphical Bus Traffic Display
Bus traffic displays use color and graphics to show captured transactions.
Packets are on separate rows. Packets receive time stamps and sequential numbers as
the system records them. Fields have labels and color codes. The system automatically
detects protocol errors and highlights them in red.
You can customize the display color scheme and field formats. You can use the hide
feature to suppress SOF packets and uninteresting user-defined packets or fields in
different contexts. You can name and save display formats for later use. Pop-up tooltips
annotate packet fields.
The display software operates independently of the hardware, allowing it to function as a
stand-alone “trace viewer” that you can freely distribute.

1.1.2 Accurate Time Measurement (Voyager, Advisor T3)
The internal counter/timer circuitry enables reliable, accurate (2 ns resolution)
time stamping of recorded bus traffic. Traces and measurement and analysis functions
display this timing information. Time fields are time stamps, idle times, bit times, or time
deltas, in either decimal or hexadecimal format. You can add any number of markers to
denote specific packets, you can make further timing measurements from one marker to
another or from marker to trigger.
An essential feature of time management is that idle traffic does not consume Analyzer
memory. Because of this unique technology, the system can make accurate timing
calculations while still preserving valuable recording memory for important bus traffic.
The oscillator has 2.5 ppm accuracy.
1.1.3 CrossSync Control Panel (Voyager, Advisor T3)
The LeCroy CrossSync control panel provides synchronization for complete end-to-end
visibility into multi-protocol systems.
CrossSync is LeCroy’s analyzer synchronization solution that enables time-aligned
display of protocol traffic from multiple daisy-chained analyzers showing packet traffic
from multiple high-speed serial busses. A lightweight software control panel allows users
to select analyzers for synchronization and manage the recording process. Captured
traffic is displayed using the latest analyzer software (in separate windows) with all the
protocol specific search and reporting features.
Captured packets are displayed in separate windows that share a common time scale.
Navigating the traffic in either direction will scroll to the same timestamp in a
synchronized window. When using the CrossSync option, users can access the full
complement of analysis capabilities available within the individual LeCroy software.
Search, reporting, and decoding all operate normally.
This feature is available with the LeCroy USB Protocol Suite application.
1.1.4 Comprehensive Error Detection and Analysis
The system detects, and alerts you to, every potential bus error and protocol violation,
and their combinations. The Analyzer BusEngine™ circuitry performs real-time triggering
on multiple error conditions, such as PID bad, bit stuffing bad, header or data CRC bad,
end-of-packet bad, babble, activity loss, frame length violation, time-out or turn-around
violation, and data toggle violation. The Analyzer program highlights all
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.

1.1.5 Real-Time Event Triggering and Capture Filtering
The Analyzer can accurately identify and selectively record transactions of interest from
the crowded stream of bus traffic. The system uses more than a dozen configurable
hardware building blocks that you can optimize to perform particular activities. Such
“recording resources” can independently await an initialization signal, monitor its external
environment (external signals or other resources) in search of a particular event, and take
a subsequent action, such as triggering, inclusive or exclusive filtering, and counting. In
the user interface, you can select, configure, and combine these resources to search for
complex trigger conditions and selectively capture associated transactions.
The system can trigger on basic events, such as specific bus conditions and
packet identifiers (PID). It can also trigger on complex events, such as “trigger on 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.”
You can set the size of the recording memory, specify the pre-trigger to post-trigger
capture ratio, and truncate large data packets up to 256 bytes.
1.1.6 Advanced Event Counting and Sequencing
The count and sequence options define rules for data recording sessions. These options
configure and control the order of events selected for triggering or filtering.
Using this feature, you can specify a sequence of up to seven events that must occur
before the Analyzer triggers and finishes capturing data, allowing you to specify
event types for recording. Without this feature, you may have to scroll through megabytes
of recorded data to locate an occurrence of a sequence.
1.1.7 BusEngine Technology
The Analyzer uses LeCroy BusEngine Technology. The BusEngine core uses Electrically
Programmable Logic Device (EPLD) technology and incorporates both a real-time
recording engine and configurable building blocks that implement data/state/error
detection, triggering, capture filtering, external signal monitoring, and event counting and
sequencing. Like the flash-memory-based firmware that controls its operation, all
BusEngine logic is fully field upgradeable, using configuration files.

1.2 Voyager M3 Analyzer
The LeCroy Voyager M3™ Analyzer and Exerciser system is a multifunction verification
system for USB 2.0 and USB 3.0 development and testing. It can record traffic and
graphically present logical USB transactions and events. It can also generate USB traffic.
The system is connected to a laptop or desktop via its USB or Gigabit Ethernet port.

USB 2.0 and USB 3.0 Features
The system can monitor traffic between USB 2.0 links using standard high-speed
compliant cables.
If configured for USB 3.0 testing, the system supports monitoring between SuperSpeed
links using USB 3.0 cables (Figure 1.3)

1.2.1 Voyager M3 General Description
The Analyzer connects to a portable or desktop PC through the USB port. The PC
configures and controls the Analyzer. The “CATC Trace™” user interface is an industry
standard for documenting the performance of high-speed serial protocols.
The USB protocol Analyzer provides traffic capture and analysis. Hardware triggering
allows capture of real-time events. Hardware filtering allows filtering different packet
types in or out of the recording. Filtering also allows you to preserve recording memory,
for extended recording time.
The trace viewer application displays recorded data in colored graphics. The application
has advanced search and viewing capabilities that allow you to quickly locate specific
data, errors, and other conditions.
The system functions with any personal computer having the Microsoft®Windows®XP,
Windows Vista™ 32, Windows Vista 64, or Windows 7 (32 or 64) operating system and
a functional USB interface or Ethernet port.
The system provides on-the-fly detection of, and triggering on, such events as Tokens
and Errors. Whether recording manually or with a specified trigger condition, the system
continuously records the link data, in a wrap-around fashion, until manually stopped or
until the system detects the Trigger Event and records the specified post-trigger amount
of link data.
Upon detection of a triggering event, the Analyzer continues to record data up to a point
specified by you. You can individually enable or disable real-time event detection to allow
triggering on events as they happen, including predefined exception or error conditions
and user-defined sets of trigger events. An externally supplied signal can trigger the
Analyzer.
You can use search functions to investigate particular events. In addition to immediate
analysis, you can print any part of the data. You can save the data on disk for later
viewing. You can generate timing information and data analysis reports.
Please refer to the Universal Serial Bus Specification for details on the protocol. The USB
specification is available from the USB Implementers Forum (USB-IF) at:
