Importance of Logging TX Equalization Settings
In addition to transceiver information, it is also important to log the host and module TX equalization settings in the test report. This ensures a comprehensive record of all relevant parameters affecting the cable’s signal integrity and performance. By including these settings, users can:
Analyze Performance: Understand how different equalization settings impact the overall performance of the cable.
Ensure Consistency: Verify that the same settings are used across different tests for accurate comparison.
Optimize Settings: Identify the optimal equalization settings for specific cables and environments.
By logging these settings, the test reports become more informative and valuable for making data-driven decisions.
Host TX Equalization Settings
For the host, the following TX equalization settings should be logged per lane per port:
Pre3 (dB)
Pre2 (dB)
Pre (dB)
Main (mV)
Post (dB)
Module TX Equalization Settings
For the module, the following TX equalization settings should be logged per lane per port:
Precursor (dB)
Amplitude (dB)
Postcursor (dB)
