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.
