NOTE
U4305A/U4305B Exerciser Card - Introduction
The Keysight U4305A/U4305B exerciser card is a test and debug tool that provides features for
testing the next generation of PCI Express technology. You can use this card to stimulate PCIe
components on system boards and cards with various test scenarios. The Exerciser card can emulate
a PCIe device or a topology with or without SRIOV / MRIOV capabilities and can provide test
conditions to test components on system boards and cards.
The U4305A/U4305B Exerciser card provides the functions of an LTSSM as well as an Exerciser to
help you perform thorough PCIe link testing and validation testing for the DUT. As an LTSSM Tester,
the Exerciser card helps you verify the DUT’s LTSSM state transitions and timeout implementations.
As an Exerciser, it exercises DUT with the configured stimulus traffic. It can send TLP requests as well
as completions to a DUT.
The U4305A/U4305B Exerciser card can emulate a PCIe endpoint and act as a Downstream
Component (DSC) for a System Under Test. It can also emulate a root complex and act as an
Upstream Component to stimulate a PCIe Device Under Test. Refer to the topics “U4305A/U4305B
Exerciser Card as an Endpoint and “U4305A/U4305B Exerciser Card as a Root Complex to know
more.
For information on installing and configuring the U4305A/U4305B exerciser
card, refer to Keysight PCIE Exerciser Gen3, Installation Guide.
For information on how to use the U4305A/U4305B exerciser card, refer to
Keysight Protocol Exerciser for PCI Express, User Guide.

Features
NOTE
U4305A Exerciser Card 1
This topic describes the features of the U4305A/U4305B exerciser card.
• It is a standard height, half-length card as described in the PCI Express specification, and fits into
every system including blade servers.
• It supports LTSSM functions for upto x16 link widths.
• It supports simultaneous use of LTSSM and Protocol Exerciser functions, without requiring any
configuration.
• It supports Gen1 (2.5 GT/s), Gen2 (5.0 GT/s), and Gen3 (8.0 GT/s) speeds as per PCIe
specifications.
• It provides non IOV, SRIOV, and MRIOV capabilities based on the licensed options.
• It supports NVMe root complex and endpoint emulation capabilities based on the licensed
options.
• You can manage, control, and use it using the Protocol Exerciser GUI and APIs.
The U4305B model of Exerciser supports L1.1 and L1.2 L1 substates in both the ASPM and
PCI-PM L1 Link states. This feature is not supported by the U4305A model.
The U4305B model uses a per-Link signal called Reference Clock Request CLKREQ# (Pin B12
of PCIe connector) for L1 substates management. Exerciser or the link partner can request a
clock power off using this signal. When the reference clock of both the link partners is
switched off, the link can go to an L1 substate.

Figure 2 U4305A/U4305B Exerciser Card components on front bracket
The hardware components displayed in the above figures of the U4305A/U4305B Exerciser card are
described:
• Edge Connector: This component is used to connect the U4305A/U4305B card with a PCIe
Connector on the backplane board, or with a system.
• Status LEDs (on board): This component has the LEDs to display the status information about the
participating lanes of the link and power status of board and exerciser card. 16 LEDs displaying
the lane status are in the upper left corner of the board and the rest of the 7 LEDs are in the upper
right corner of the board. The module number to which U4305A/U4305B is configured is also
displayed in the upper left corner.
To get a description of each LED on the board, refer to the topic “Exerciser Card Status LEDs in
this chapter.
• Status LEDs (on front bracket):
The green LED represents the link speed status and has the following different states:
• No light means there is no link up between the Exerciser card and DUT.
• Green light means there is a link up at the Gen3 speed (8.0 GT/s).
• Fast blinking light means there is a link up at the Gen2 speed (5.0 GT/s).
• Slow blinking light means there is a link up at the Gen1 speed (2.5 GT/s).
The red LED on the front bracket will be on until the FPGA receives a valid configuration.

CAUTION
NOTE
• USB Connector: This component is used to connect U4305A/U4305B with the controller PC using
the USB cable.
• Power Supply Connector: This component is used to connect U4305A/U4305B with the external
power supply. Use the power supply delivered with U4305A only.
• TRIG OUT Connector: This component is used to connect the U4305A/U4305B card with other test
equipments such as Protocol Analyzer to trigger these test equipments. The Exerciser card
generates a trigger out pulse when a specified trigger out condition is met.
• TRIG IN Connector: This component is used to connect the U4305A/U4305B card with other test
equipments such as Protocol Analyzer to receive a trigger from these test equipments when a
specified condition is met.
The electrical characteristics of the Trigger In/Out are as follows:
• Trigger In: Vin Low Max = 0.9V, Vin High Min = 2.0V max, Input current +/- 5uA. The width of
the trigger in pulse should be greater than 32 ns.
• Trigger Out: TTL levels series terminated with 50 Ohms. Vout High Min (no load termination) =
2.4V, Vout Low Max (no load termination) = 0.4V; Vout High Min (with 50 Ohms External
termination to GND) = 1.2V, Vout Low Max (with 50 Ohms External termination to GND) = 0.2V.
The width of the trigger out pulse is 125 ns.
Do not directly touch any component on the U4305A/U4305B exerciser card. It
may be hot.
This component comes with a protective foam cover to protect it from electrostatic damage
(Figure 3).

Components on the U4305A/U4305B exerciser card are sensitive to the static
electricity. Therefore, take necessary anti-static precautions, such as wear a
grounded wrist strap, to minimize the possibility of electrostatic damage.
Please remove the protective foam cover before using the card, and attach it
again when the card is not in use.

U4305A/U4305B Exerciser Card as an Endpoint
NOTE
This topic introduces you to the U4305A/U4305B exerciser card emulating a PCIe endpoint.
For detailed information on how to set up the U4305A/U4305B exerciser card as
a PCIe endpoint, refer to the Keysight PCIE Exerciser Gen3 Installation guide.
You can use the U4305A/U4305B exerciser card as an endpoint to stimulate a System Under Test
into various test scenarios. To accomplish this, you plug the exerciser card as a normal PCIe device
into the motherboard under test through the Edge connector of the card.
A controller system hosts the Protocol Exerciser software and hardware support services to control
and manage the Exerciser card. Exerciser card is connected to this controller system through a USB
cable. The following figure displays a sample hardware setup in which the U4305A/U4305B exerciser
card is emulating a PCIe endpoint.

U4305A/U4305B Exerciser Card as a Root Complex
This topic introduces you to the U4305A/U4305B exerciser card emulating a root complex.
For detailed information on how to set up the U4305A/U4305B exerciser card as
a root complex, refer to the Keysight PCIE Exerciser Gen3 Installation guide.
You can use the U4305A/U4305B exerciser card as a root complex to stimulate a DUT into various
test scenarios. To accomplish this, you plug the exerciser card into a passive backplane board
through the Edge connector of the card. In this case, the Exerciser card communicates to the DUT
through the bottom connectors.
A controller system hosts the Protocol Exerciser software and hardware support services to control
and manage the Exerciser card. Exerciser card is connected to this controlling system through a USB
cable. The following figure displays a sample hardware setup in which the U4305A/U4305B exerciser
