About SuperSpeed USB
Developed and promoted through the
USB Implementers Forum (USB-IF),
USB has been long established as
the interconnect system of choice
for peripheral systems.
SuperSpeed USB is backwards
compatible with USB 2.0, ensuring
a smooth adoption path for all
users. However, for developers the
challenges of USB 3.0 are daunting.
High-speed gigabit serial data links
require new design approaches, high
quality manufacturing processes, and
comprehensive testing and debug
procedures to achieve reliable data
transfer and interoperability.

The SuperSpeed USB Compliance
Test Specification requires the use
of reference channels and continuous
time linear equalization (CTLE) for
compliance measurements. The
SDA 813Zi-A with the Eye Doctor II
analysis package has the ability to
emulate the reference channel and
the CTLE as specified for both
compliance measurements and to
troubleshoot the root cause of
compliance failure.
Another of the new SuperSpeed
USB capabilities is Optimized Power
Management which requires all

development and test of this feature
requires equipment that is able to
simultaneously monitor both physical
and protocol levels.
The Power Tracker option for the
Voyager USB 3.0 Protocol Analyzer
simultaneously captures both protocol
traffic and power consumption,
allowing engineers to quickly isolate
and identify problems in ensuring
compliance to the new power
management requirements.

The Perfect Oscilloscope for
SuperSpeed USB Testing
The LeCroy SDA 8 Zi-A Series of
oscilloscopes with the Eye Doctor II
analysis package are the perfect
instruments for performing
SuperSpeed USB compliance
measurements and more importantly
for debugging compliance failures
allowing the engineers to quickly find
the root cause of serial data problems.
Eye Doctor II provides the channel
emulation, de-embedding and
equalization tools that engineers
need for next generation serial data
standards. These features are required
for SuperSpeed USB testing since
a compliance test channel must
be emulated and the signal must be
equalized using a Continuous Time
Linear Equalizer prior to eye diagram
and jitter analysis. SDA II allows the
user to quickly create eye diagrams
utilizing the full record length of the
oscilloscope, and perform jitter
analysis accurately, even when there
is a very long non-repeating pattern.
Additionally, SDA II has two different
jitter breakdown methodologies and
the deepest jitter analysis toolbox for
correctly identifying sources of jitter.
Also, SDA II has unique eye diagram
analysis tools, such as IsoBER, for
providing even deeper insight into
eye diagrams.
The SDA 8 Zi-A Series of oscilloscopes
provides the best asset investment
protection available. With the widest
bandwidth upgrade range, an engineer
who is working on 2nd generation
technologies today can confidently
know that WaveMaster 8 Zi-A will
support 3rd or 4th generation
technology needs several years from
now. Also, the SDA 8 Zi-A Series of
oscilloscopes has the lowest jitter
noise floor for SuperSpeed USB
measurements.

including screenshots.
QPHY-USB3-Tx-Rx uses all of the
powerful oscilloscope features to
perform the compliance tests as
described by the USB 3.0 Electrical
Test Specification.
Using the PeRT 3 Phoenix
for Transmitter Testing
Transmitter link equalization
response test requires the test
instrument to handshake with the
DUT in the protocol layer to test
the DUT’s response to different
equalization setting requests.
LeCroy PeRT3 Phoenix is specifically
designed to address this requirement
for PCI Express Gen3.

PeRT 3 Test System
The PeRT 3 (Protocol-enabled Receiver
and Transmitter Tolerance Tester) fills
the space between physical layer
test and protocol test, providing a
new and more intelligent capability for
performance testing of receivers and
transmitters. Designed to meet the
test needs of engineers working with
serial data transceivers and other highspeed
serial data communication
systems, the LeCroy PeRT3 Test
System is not just a new instrument,
it is an entirely new instrument class.
Complete Characterization in
Development or Automated
Test Environments
The PeRT3 is designed to test
receivers under conditions of stress
by starting with a clean signal and
gradually introducing measured levels
of a variety of different stress types
into the signal, and simultaneously
monitoring the bit error rate (BER) to
explore the full performance envelope
of the receiver system.
Because the system is able to
interpret and generate protocol traffic,
the PeRT 3 is uniquely able to manage
fully-automated testing of USB 3.0
products. For example, the PeRT3 can initialize the remote device and
command the device to enter or exit
loop-back mode while testing is in
progress. In addition, the PeRT3 is
capable of intelligently managing
automated testing through events
which disrupt other test systems,
such as the addition or deletion of
SKP symbols by devices in the data
traffic pattern.
The PeRT3 allows you to extend
testing into protocol areas, such as
measuring CRC errors, frame errors
and other protocol-specific criteria

while actively adding measured
amounts of stress into the signal,
such as increased jitter and noise.
With a single integrated system,
the PeRT3 replaces up to 6–8 other
instruments and greatly simplifies
experimental setup, increases the
ease of designing and conducting
fully automated testing, and provides
specific test suites to ensure receiver
compliance to USB 3.0 specifications.
Calibrating the Jitter
Output of the PeRT3 Receiver test specifications
require calibration of the jitter
output sources for the test
instrument. When using the
PeRT3 in conjunction with
SDA 8 Zi-A oscilloscope, this
calibration is done automatically
by the QPHY-USB3-Tx-Rx
application.

Fully automated SuperSpeed USB Transmitter and Receiver Testing.
When combining the power of the SDA 8 Zi-A Oscilloscope with the
unique features of the PeRT3 the perfect test setup for SuperSpeed USB
compliance test is created.
When using the SDA 8 Zi-A
oscilloscope for transmitter only
testing, the user is still required to
stimulate the product under test
to output the required test patterns
for each of the transmitter tests.
Likewise, when using the PeRT3 for receiver only testing, the
specification requires the user to
calibrate the jitter output sources
prior to performing the receiver
test. By making the appropriate
connections to the USB-IF test fixture,
the SDA 8 Zi-A oscilloscope and PeRT3 can uniquely interoperate to achieve
the fastest and most accurate
SuperSpeed USB product qualification.
All of these test results are then
combined into a single test report.
PeRT3 Value in
Transmitter Testing
Although, the PeRT3 is primarily
used for receiver testing, it can also
be used to communicate with the
product under test on the protocol
layer (Ping.LFPS commands) to
stimulate it to output the required
compliance patterns for transmitter
tests. The transmitter of the PeRT3 For more information on the USB 3.0
test capabilities of the SDA 813Zi-A and
QPHY-USB3-Tx-Rx, see the document

can be connected to the receiver
of the product under test, while
the transmitter of the product
under test is connected to the
oscilloscope channels. Using this
setup, the SDA 8 Zi-A oscilloscope
and the PeRT3 can be combined
for automating all of the required
transmitter tests.
SDA 8 Zi-A Value in
Receiver Testing
Also, the SDA 8 Zi-A oscilloscope
is used primarily for testing
transmitters, but calibration of the
jitter output sources of the PeRT3 is required by the receiver test
specification. Following the calibration
procedure, the transmitter of the
PeRT3 can be routed through the
compliance test channel to the
oscilloscope channels instead of
the product under test. Once the
calibration is completed, the
transmitter of the PeRT3 can be
routed instead to the receiver of
the product under test through the
compliance test channel. Using
this setup, the PeRT3 and the
SDA 8 Zi-A oscilloscope can be
combined for automating all of
the required receiver tests.

Testing USB3.0 Data Channels with the LeCroy SPARQ
USB3.0 Tx, Rx and cable compliance tests that measure insertion loss,
impedance and crosstalk measurements can be made with the LeCroy
SPARQ. The SPARQ is a new class of instrument; the Signal Integrity
Network Analyzer. SPARQ, which stands for “S-parameters Quick,” is
a TDR/TDT-based analyzer that measures 40 GHz, 4-port S-parameters
with a single button press, and at a fraction of a cost of a VNA. Fully
calibrated measurements can be made in minutes, and without any need
to connect or disconnect cables to calibration kit standards or electronic
calibration modules.
The SPARQ’s single button press
operation is accomplished by utilizing
the industry’s first built-in OSLT
calibration kit. The SPARQ performs
the OSLT calibration automatically,
without any user intervention,
eliminating the frustration VNA users
have with error-prone manual
calibration procedures and expensive
“ECAL” modules. In addition to
S-parameter results, SPARQ calculates
step and impulse responses and Rho
and Z profiles normalized to a user’s
risetime. All measurements can be
made in both single-ended and mixedmode
configurations, yielding the
differential insertion loss, crosstalk
and impedance measurements
needed for USB 3.0 Tx/Rx and
cable compliance testing. Results
are “simulation ready”, using
passivity, reciprocity and causality
enforcements, and results include
a DC point, something that cannot
be done with a VNA. All of these
features are standard.
To achieve its low price and superior
ease-of-use, the SPARQ utilizes a
high-bandwidth switch matrix to route
fast TDR pulses (6 ps rise time) and
TDT responses to the internal

Calibrated impedance measurements are available with selectable rise time. This feature provides compliant impedance measurements
of connectors, cables, and backplanes.
calibration kit and to the DUT. This
architecture is cost-effective, and
provides the single button press
operation. The measurement’s reference
plane is moved to the DUT via an
algorithm that de-embeds the switch
matrix and other external components,
such as cables, adapters and test
fixture. The SPARQ uses LeCroy’s
“CIS” timebase to acquire waveforms
about 20 times faster than other TDR
solutions. This results in faster averaging,
without linearity issues. Additionally, a
wavelet denoising algorithm further
eliminates noise, yielding the highest
dynamic range of any TDR/T-based
network analyzer (50 db @ 40 GHz).

Transmitter DC Differential Impedance
Transmitter DC Common Mode Impedance
Receiver DC Differential Impedance
D+/D- Pair Attenuation

LeCroy’s Voyager USB 3.0 protocol verification platform is an essential
test system for teams designing Certified USB 3.0 products. A full
func tion analyzer, it is capable of recording and analyzing traffic between
both USB 2.0 or 3.0 devices. The integrated exerciser is capable of
emu lating USB 2.0 and 3.0 device behaviors to allow functional,
reliability, and performance testing. By leveraging LeCroy’s expertise
developed for our PCI Express 5 Gb/s protocol testers, the Voyager has
emerged as the preeminent system for USB 3.0 compliance verification.
Complete Solution
Designed from the start to address
compliance testing, the Voyager
platform is available with an advanced
exerciser capable of both USB 2.0 and
3.0 host and device emulation. The
exerciser allows users to transmit
custom packets over standard USB
cables with low-level control of
headers, payloads, timing, and link
states. The exerciser is capable of
directing devices into specific logical
states where low level protocol rules
can be verified. It is seamlessly
integrated with the protocol analyzer,
making this system ideal for
“cradle-to-grave” USB 3.0 validation.
USB Compliance Suite
The Voyager analyzer-exerciser system
is now available with a protocol
compliance suite for USB 2.0 and 3.0.
Designed to allow developers to pretest
devices for USB conformance,
the system uses USB traffic emulation
scripts to generate specific traffic
conditions and analyze the response
from the DUT. The compliance suite
provides link layer test coverage (Ch.7)
for USB 3.0 hosts and devices to verify
proper link training, handshaking and
recovery behaviors. Framework test
coverage (Ch.9) is also provided for
USB 2.0 and 3.0 devices.

Compliance Reports
The Compliance Suite provides
“one-button” operation that manages
the Voyager test system and runs all
the verification software. After each
test case is run, the system displays a
pass/fail result. If a test should fail, the
system can automatically save trace
files to help users identify root cause
i ssues. Markers with a description of
the error are automatically inserted
on the packet in question. After
each session, reports can be
generated in HTML, XML or text.
Full source code is provided allowing
individual scripts to be modified for
custom verification tasks.
Verifying Power
Management
USB 3.0 power management support
is implemented at the link layer which
adds new behaviors that must be
thoroughly tested. The Voyager
records and timestamps all upstream
and downstream power state changes.
The Compliance Suite adds specific
test cases that verify power
management protocol including
proper entry and exit. Power Tracker
is a separate report that measures
vBus amps and helps users correlate
actual power usage with logical link
state changes.

Flexible Test
Development
For custom test development,
the exerciser uses script-based
instruc tions to send specific patterns
or commands to the DUT. A flexible
control language provides re-usable
frame templates and field definitions
that make it easy to expand the tests
for custom scenarios. Low latency
handshakes are automatic thanks
to ReadyLink — a full link layer
emulation mode built in to the
exerciser. It automatically handles
all USB 3.0 flow control and allows
the exerciser to operate like a real
SOC device.
