5 Tuning the Analyzer for a Specific DUT

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.
