U4305B-EX3 PCIe Gen3 Exerciser (Continued)
As an endpoint
When emulating an endpoint, the Keysight U4305B Gen3 exerciser card is plugged into
a PCIe slot on the motherboard, as a normal PCIe device. In this scenario, the exerciser
card can be used to perform load and stress testing of the system under test.
As a root complex
When emulating a root complex, the Keysight U4305B Gen3 exerciser card
communicates with the device under test through the Keysight N5316A backplane
board. In this configuration, the exerciser communicates to the DUT through the bottom
connectors. The DUT receives its power from the backplane.
Figure 6 shows example setups of a protocol exerciser card emulating an endpoint and a
root complex.
