Overview
PCIe 3.0 exerciser can help you validate your device whether it is a server or an add-in card. The emulated personality
is easily switched through software for either a root complex or an end point. It has support for PCIe, MRIOV, SRIOV
protocols. www.keysight.com/find/pci-express
Current OSes supported
Windows XP 32/64, Windows 7 32/64
Important usage notes
Refer to Help for details on how to install and use this package.
1. If you have USB Device(s) (U4305A) attached to your system but only one or none of them receives a valid module
number (module numbers on the U4305A devices are 10001, 10002 etc.), this might be due to one of the
following reasons:
Readme for Keysight U4305A Protocol Exerciser for PCI Express Gen3
a. The USB Device(s) has been plugged in for the first time after rebooting the host controller PC and another
USB Device or module was already locked by a session. Please close all existing sessions and update the
module numbers. Now run Start->Programs->Keysight SPT->Tools->Diagnostics and hit the button 'Update
Module Numbers'.
b. If you are working on a system with Windows XP SP2 this might be a problem with the loopback addresses.
This has been fixed by Microsoft in the patch KB893066. You can download the patch at the Microsoft site
http://www.microsoft.com/downloads/
2. If your USB controller supports USB2.0 make sure that you use the delivered (or corresponding) USB2.0 cable
only.
3. Release 7.3(E2960B Gen2 Exerciser) & Release 8.x (U4305A Gen3 Exerciser) cannot exist on same machine.
4. If you don't see modules after updating Firmware then restart AgtN2XUSBManagerService &
AgtN2XResourceManager.
5. Windows 7 support
a. Run the installer exe in Administrator Mode
b. User Account control Settings should be "Never notify"
6. The location of the OpenE script has been changed from 'C:\AgilentPciExpress' to \8.x
Release\Samples\PCIe Port.
7. PTC works at x1 link-width. Higher lanes might be required to be physically masked for DUTs with higher link-
widths.
8. It is observed that error message "Failed to generate pkgIndex.tcl for dir \lib\KeysightN2X" gets displayed in case
installation/un-installation steps were not done in the proper sequence. In such cases, please do the following:
a. Open "Add or Remove Programs" (Windows XP) or "Programs and Features" (Windows 7) from Control Panel
and uninstall the following products:
- Keysight SPT Platform
- Keysight SPT Tcl/Tk 8.3.4 with Extras
- Keysight SPT PCIE Exerciser Gen3(8.70 Release)
b. Install the Keysight SPT PCIE Exerciser Gen3 software again.
9. Added the ability to uninstall licenses for Keysight internal processes. Keysight recommends that the following
should not be performed on a customer unit unless directed to do so by an Keysight support engineer. Licenses
can be uninstalled using the License install dialog in the Exerciser GUI and also through the API using the
following procedure:
a. Open the Exerciser and open a new session and add the port of the Exerciser for which the licenses need to be
cleared.
b. Open the License install dialog using the File > Software Packages menu option.
c. Enter the key DADADADA-DADADADA in the `Enter License Key' text box. The value of the `Select Package'
dropdown is not used and can be left as it is.
d. Click Apply. The message "The license...was successfully installed' will be shown. All the licenses have been
now removed.
e. Close the Exerciser GUI and also close the session and reopen the Exerciser and session to verify.
f. Please note that this removes all licenses on the Exerciser board. Use this option with caution.
g. The above procedure can also be done using the API `SWPackageInstall'. Here is the Tcl syntax:
AgtInvoke AgtSptCommon SWPackageInstall 1 "U4305A-EX3" "DADADADA-DADADADA"
10. Added the U4305A-000 license. This license is available for Keysight U4305A demo units only. The U4305A-000
license key needs to be generated using the Keysight internal license generator and installed using the API. The
following is the Tcl syntax:
AgtInvoke AgtSptCommon SWPackageInstall 1 "U4305A-000" "<>"
11. Exerciser drivers are now copied on to the installation folder during installation. They are located in the folder
`C:\Program Files (x86)\Keysight\SPT\PCIEExerciserGen3\8.74 Release\Drivers' in Windows 7 64 bit and in
`C:\Program Files\Keysight\SPT\PCIEExerciserGen3\8.74 Release\Drivers' in Windows XP/7 32 bit. To install the
driver, copy the appropriate driver to any folder in the SUT and start `dpinst.exe' found in the copied folder. Please
follow the on screen instructions and the driver will be installed.

12. Installation of drivers may fail on some Windows XP systems. This may be because of some root certificates not
being present on the system. The root certificates need to be downloaded and installed in order to fix this. Here
are the steps:
a. Open the following link http://www.verisign.com/support/roots.html.
b. Download the Verisign Root Package `roots.zip' from the above website.
c. Extract the zip file and open the folder "VeriSign Root Certificates\Generation 5 (G5) PCA\".
d. This folder will contain the file "VeriSign Class 3 Public Primary Certification Authority - G5.cer". Right click and
select "Install Certificate". Follow the onscreen instructions. Please select the default settings and ignore the
warnings which are displayed.
e. Now try installing the required drivers.
