03 | Keysight | U4305B Protocol Exerciser for PCI Express^® 3.0 - Data Sheet
Overview
–– Supports Gen1 (2.5 GT/s), Gen2 (5.0 GT/s), and Gen3 (8.0 GT/s) speeds
–– x1, x2, x4, x8, or x16 link widths
–– Standard height, half-length card
–– Perform thorough PCIe^® Link testing
–– Power management testing of L0s, L1, and L1 substates.
The Keysight U4305B Exerciser can be configured to provide sub-protocol layer test and
debug for legacy and next generation PCIe devices. The U4305B Exerciser for PCIe is
an advanced traffic generator that can be used to send and respond to TLP, DLLP, and
physical layer packets to stimulate PCIe devices and systems. The Exerciser operates
in one of three modes, PCIe, MR-IOV, or SR-IOV. The capabilities of these modes can
be enhanced with the purchase of additional software licenses. Specific DUT test case
requirements can be written by means of the included API. U4305B is a standard height,
half-length PC form factor card as described in the PCI Express specification, and fits
into every system including blade servers.
The PCI Express test and debug capabilities of the U4305B is broken down into the
sub-protocol layers of the specification as shown in Figure 3. By emulating a PCIe
component (with or without MRIOV capabilities), the Keysight U4305B Exerciser acts
as an ideal link partner by sending appropriate I/O traffic to stimulate the device under
test. The device under test can be exercised under various conditions and scenarios
without influencing the performance parameters of the device under test. The Keysight
U4305B Exerciser can send a block of TLP requests of 32- or 64-bit memory, I/O,
Configuration, or Message types as stimulus to the device under test. It can also be used
to send completion packets in response to DUT’s requests.

Simple controls for traffic generation and error detection or insertion are simple to access and
configure.
