Specifying the Connection Setup 3
U4328A M.2 (M-key) Interposer
When used with a U4328A M.2 (M-key) Interposer, one U4301A/B module can probe a x1, x2, or x4
bidirectional PCIe link configuration (as per the M.2 specifications).
To reflect such a probing hardware setup in the Connection Setup tab of the Logic and Protocol
Analyzer application, you need to select the U4328A M.2 (M-key) Interposer as the probing option
and Bidirectional as the link type for the U4301A/B module. The link width can be selected as x1, x2,
or x4.
U4330A U.2 (SFF-8639) Interposer
When used with a U4330A U.2 Interposer , one U4301A/B module can probe a Single Port
Configuration that is, a single x1, x2, or x4 unidirectional or bidirectional PCIe link (as per the U.2
SFF-8639 interconnection standard).
To reflect such a probing hardware setup in the Connection Setup tab of the Logic and Protocol
Analyzer application, you need to select the U4330A U.2 SFF-8639 Interposer as the probing option.
The link width can be selected as x1, x2, or x4.
To specify the connection setup
1 In the Keysight Logic and Protocol Analyzer application's Overview window, from the PCIe
analyzer module's drop-down menu, select Setup>Setup... .
2 From the Footprint Listbox , select the type of probing that you have set up between the U4301A/B
Analyzer module and DUT. For each of the supported four probing types, different probing
options are available in the Footprints listbox based on the data direction (upstream,
downstream, or bidirectional). Based on your probing setup and the link type needed, select an
appropriate probing option from the Footprint listbox. Refer to the “Probing options" on page 21
to know more about these options.
