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.

NOTE

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.

U4305A Exerciser Card 1

Features

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.

NOTE

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.

Components

This topic describes the hardware components of the U4305A/U4305B exerciser card.

Figure 1 and Figure 2 display the U4305A/U4305B exerciser card to indicate the various components

of this card.

Keysight Protocol Exerciser for PCI Express Hardware Guide 15

U4305A Exerciser Card 1

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.

•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.

This component comes with a protective foam cover to protect it from electrostatic damage

(Figure 3).

Figure 3 Protective Foam Cover for Edge Connector

Exerciser Card Status LEDs

The U4305A/U4305B Exerciser card has a number of status LEDs on the board and on the front

bracket. This topic describes the meaning of each of these status LEDs.

The following figure displays the status LEDs on board.

WARNING

Do not directly touch any component on the U4305A/U4305B exerciser card. It

may be hot.

CAUTION

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.

NOTE

Please remove the protective foam cover before using the card, and attach it

again when the card is not in use.
