About This Manual
This manual assumes that you are familiar with using an oscilloscope−in particular the Teledyne
LeCroy oscilloscope that will be used with QualiPHY−and that you have purchased the QPHYPCIE software option. Some of the images in this manual may show QualiPHY products other
than QPHY-PCIE, or were captured using different model oscilloscopes, as they are meant to
illustrate general concepts only. Rest assured that while the user interface may look different
from yours, the functionality is identical.

Introduction
About QualiPHY
QualiPHY is a highly automated compliance test software meant to help you develop and
validate the PHY (physical-electrical) layer of a device, in accordance with the official
documents published by the applicable standards organizations and special interest groups
(SIGs). You can additionally set custom variables and limits to test compliance to internal
standards.
QualiPHY is composed of a “framework” application that enables the configuration and control
of separate tests for each standard through a common user interface. Features include:
• Multiple Data Source Capability: Connect to your X-Stream oscilloscope via LAN or
other interfaces.
• User-Defined Test Limits: Parameter interconnect losses can be factored into the
parametric results.
• Flexible Test Results Reporting that includes XML Test Record Generation.
Understand a device performance distribution, or obtain process related information from
the devices under test.
About QPHY-PCIE
QPHY-PCIE is an automated test package performing all the normative, real-time oscilloscope
tests for sources in accordance with PCI Express Card Electromechanical Specification, Rev.
3.0.
The software can be run on any Teledyne LeCroy real-time oscilloscope with at least 6 GHz
bandwidth for 2.5 GT/s testing and 13 GHz for 5.0 GT/s testing.
Required Hardware
• Real-time Teledyne LeCroy oscilloscope with the QualiPHY software and an activated
QPHY-PCIE component
• 2 pair standard SMA-SMA cables for Gen 1 fixtures
• 1 pair standard SMA-SMP cables for Gen 2 fixtures
• PCIE base board (CBB) for testing system boards
• PCIe load board (CLB) for testing add-in cards
For the most complete and up-to-date list, see the PCI SIG website:

Test Fixtures
The PCI Express standard describes a set of two fixtures used for connection to the signal
under test: the compliance load board (CLB) used to test system boards and the compliance
base board (CBB) used to test add-in cards. Both the CLB and CBB are available through the
PCI special interest group (PCI-SIG) at www.pcisig.org. Fixtures that are compliant with
Revision 1.1 of the Base and CEM Specifications are required to execute QPHY-PCIe tests for
Gen 1 add-in cards and system boards; likewise, f ixtures compliant with Revision 2.0 of the
specifications are required to execute tests for Gen 2 devices.
Using SMA type cables with t he Gen 1 fixtures, or SMA-to-SMP type cables with the Gen 2
fixtures, allows positive and negative line attachment of the differential signals directly to
separate channels on the instrument. The fixtures are designed to apply the compliance test
load to the ports of the device under test. The CBB provides a 100 MHz system clock used by
add-in cards plugged into the fixture and a socket for a standard ATX power supply.
The 50 Ω impedance on each oscilloscope channel provides the proper loading for compliance
testing. All PCI Express add-in cards and system boards must transmit a standard compliance
pattern when loaded with 50 Ω to ground on each line – all while no signal is being received.
The compliance load board (CLB1) provides probing access for 1, 4, 8 and 16 lane connectors
that connect to Gen 1.1 system boards. This is used for testing system boards that only perform
at 2.5GT/s.

The compliance base board (CBB1) provides probing access for 1, 4, 8 and 16 lane connectors
that connect to Gen 1.1 add-in cards. This is used for testing add-in cards that only perform at
2.5GT/s.

The compliance load board (x1/x16 CLB2) provides probing access for 1 and 16 lane
connectors that connect to Gen 2.0 system boards.

The compliance load board (x4/x8 CLB2) provides probing access for 4 and 8 lane connectors
that connect to Gen 2.0 system boards.

The compliance base board (CBB2) provides probing access for 1, 4, 8 and 16 lane connectors
that connect to Gen 2.0 add-in cards. Also, the CBB2 provides a clean reference clock and
clock noise injection capabilities.

Required Host Computer System
Usually, the oscilloscope is the host computer for the QualiPHY software, and all models that
meet the acquisition requirements will also meet the host system requirements. However, if you
wish to run the QualiPHY software from a remote computer, these minimum requirements apply:
• Operating System:
o Windows 2000 Professional with service pack 4
o Windows XP Professional with service pack 2
o Windows VISTA with service pack 1
o Windows 7 Professional
• 1 GHz or faster processor
• 1 GB (32-bit) or 2 GB (64-bit) of RAM
• Ethernet (LAN) network capability
• Hard Drive:
o At least 100 MB free to install the framework application
o Up to 1GB per standard installed to store the log database (each database grows
from a few MB to a maximum of 1 GB)
See Set Up Remote Control
for configuration instructions.
