Safety Summary

The following general safety precautions must be observed during all phases of operation of this

instrument. Failure to comply with these precautions or with specific warnings or operating

instructions in the product manuals violates safety standards of design, manufacture, and intended

use of the instrument. Keysight Technologies assumes no liability for the customer's failure to comply

with these requirements. Product manuals are provided with your instrument on CD-ROM and/or in

printed form. Printed manuals are an option for many products. Manuals may also be available on

the Web. Go to www.keysight.com and type in your product number in the Search field at the top of

the page.

General Do not use this product in any manner not specified by the manufacturer. The protective features of

this product may be impaired if it is used in a manner not specified in the operation instructions.

Before Applying

Power

Verify that all safety precautions are taken. Make all connections to the unit before applying power.

Note the instrument's external markings described in “Safety Symbols”.

Ground the

Instrument

If your product is provided with a grounding type power plug, the instrument chassis and cover must

be connected to an electrical ground to minimize shock hazard. The ground pin must be firmly

connected to an electrical ground (safety ground) terminal at the power outlet. Any interruption of

the protective (grounding) conductor or disconnection of the protective earth terminal will cause a

potential shock hazard that could result in personal injury.

Fuses See the user's guide or operator's manual for information about line-fuse replacement. Some

instruments contain an internal fuse, which is not user accessible.

Do Not Operate in

an Explosive

Atmosphere

Do not operate the instrument in the presence of flammable gases or fumes.

Do Not Remove the

Instrument Cover

Only qualified, service-trained personnel who are aware of the hazards involved should remove

instrument covers. Always disconnect the power cable and any external circuits before removing the

instrument cover.

Cleaning Clean the outside of the instrument with a soft, lint-free, slightly dampened cloth. Do not use

detergent or chemical solvents.

Do Not Modify the

Instrument

Do not install substitute parts or perform any unauthorized modification to the product. Return the

product to a Keysight Sales and Service Office for service and repair to ensure that safety features

are maintained.

In Case of Damage Instruments that appear damaged or defective should be made inoperative and secured against

unintended operation until they can be repaired by qualified service personnel.

CAUTION

A CAUTION notice denotes a hazard. It calls attention to an operating procedure, practice,

or the like that, if not correctly performed or adhered to, could result in damage to the

product or loss of important data. Do not proceed beyond a CAUTION notice until the

indicated conditions are fully understood and met.

WARNING

A WARNING notice denotes a hazard. It calls attention to an operating procedure,

practice, or the like that, if not correctly performed or adhered to, could result in

personal injury or death. Do not proceed beyond a WARNING notice until the indicated

conditions are fully understood and met.

U4301A/B PCIe Gen3 Analyzer—At a Glance

The U4301A/B PCIe Gen3 analyzer lets you capture and decode PCI Express 3.0 (PCIe 3.0) data and

view it in a Protocol Viewer window. The protocol analyzer supports all PCIe 3.0 speeds, including 2.5

GT/s (Gen1) and 5.0 GT/s (Gen2) through PCIe 8 GT/s (Gen3), and it supports link widths from x1 to

x16.

The U4301B PCIe Gen3 analyzer provides enhanced PCIe Gen3 features over the U4301A analyzer.

You can install the U4301B module in a Keysight AXIe chassis (for example, the M9502A 2 slot

chassis). The U4301A module can be installed in a Keysight Digital Test Console chassis (for

example, the U4002A portable 2-slot chassis) or a Keysight AXIe chassis (for example, the M9502A 2

slot chassis).

When a controller PC is connected to a Keysight chassis via an external PCIe interface and cable, the

Keysight Logic and Protocol Analyzer application (running on the controller PC) lets you connect to

the chassis, set up U4301A/B PCIe Gen3 analyzer data captures, and perform analysis.

The U4301A/B PCIe Gen3 analyzer provides:

Effective presentation of protocol interactions from physical layer to transaction layer:

• Industry standard spreadsheet format protocol viewer with:

• Highlighting by packet type or direction.

• Easy flow columns to better understand the stimulus and response nature of the protocols.

• Context sensitive columns to show only the relevant information, minimizing the need to

scroll horizontally.

• Flexible GUI configuration to meet debug needs, with pre-defined GUI layouts for Link Training

debug, Config accesses, and general I/O.

Simple and powerful state-based triggering:

• New simple trigger mode makes it easy to setup single event triggers.

• Powerful state-based triggering including:

• Four states supported in trigger sequencer.

• Triggering on patterns (ordered set patterns or packet types).

• Internal counters and timers.

• Triggering on an ordered set on a specific lane.

• External trigger in/out.

Powerful hardware features ensure capture of important transition events:

• Dual phase lock loops (PLLs) per direction ensuring that the analyzer will lock on speed change

events quickly and not miss any critical data.

NOTE

You can upgrade your U4301A module and enhance its PCIe Gen3 features by using the System

level upgrade license (U4301U-GFP). This license includes a system level upgrade of the U4301A

module to match the features available with the latest U4301B module. This upgrade includes 8

GB Capture Buffer, LTSSM Viewer, Transaction Decoder, and Offline Performance Summary

features.

If there are multiple U4301A modules in a chassis, then installing the System Level Upgrade

license on one of these modules enables features such as LTSSM Viewer, Transaction Decoder,

and Offline Performance Summary on all the U4301A modules in the chassis. The capture buffer,

however, is upgraded only for the U4301A module on which the system level upgrade license has

been installed and not for all the U4301A modules in the chassis.

8Keysight U4301 PCIe Gen3 Analyzer User’s Guide

• 8 GB capture buffer for a U4301B module. 4 GB capture buffer for a U4301A module. This can be

upgraded to 8 GB if the System Level Upgrade license is installed on the U4301A module.

• PCIe Gen1 x4 link to the host PC, provides up to 10 Gbps of data download.

• LEDs to show lane status and speed for fast understanding of current link status.

Cross-triggering with an external oscilloscope and making time-correlated measurements (using

markers).

• You can display data captured by the oscilloscope in the Waveform and Listing display windows.

This external oscilloscope correlation and data display feature is also referred to as View Scope.

To know more about this feature and how to use it with the U4301 Analyzer, refer to the External

Oscilloscope Time Correlation and Data Display Online Help.
