Creating a Physical Layer Tuning File
After you have prepared your system for tuning and configured the connection setup for the
U4301A/B module, you can create a physical layer tuning (.ptu) file. This file stores the information
about the test setup (lane inversions, number of lanes, etc) and the tuning parameters that were
discovered during tuning. You use this file in the PCIe Analyzer setup in the Logic and Protocol
Analyzer GUI to tune the system.
To create a physical layer tuning file
Perform these steps on the host PC that is physically connected to the U4301 Analyzer module.
1 Exit the
Keysight Logic and Protocol Analyzer application if it is currently active.
2 Start the Keysight Logic and Protocol Analyzer application.
This is done to ensure that all the default settings in the analyzer software are used.‘‘‘
3 In the Logic and Protocol Analyzer GUI’s Overview window, select Setup>Setup... . from the PCIe
analyzer module's drop-down menu to access its Setup dialog box.
4 Click the Phy Tuning tab of the Setup dialog box.
