Document Table of Contents Determining the Best Tap Settings

To determine the best tap settings using decision feedback equalization (DFE):
  1. Use Auto Sweep to find optimal PMA settings, while leaving the DFE mode set to Off.
    Option Description
    If BER = 0 Use the best PMA settings achieved.
    If BER > 0 Use this PMA setting, and set the minimum and maximum values auto sweep reports to match this setting. Set the maximum DFE range to limits for each of the three DFE settings.
  2. Click Create Report to view the results and determine which DFE setting has the best BER. Use these settings in conjunction with the PMA settings for the best results.
