  Analyzer displays the eye diagram correctly, but the calculated parameters are all zero.
  
  The results are:
  
  Max. Q Factor = 0
  Min. BER = 1
  Eye Height = 0
  Threshold = 0
  Decision Instant = 0
  
  Although the eye diagram is visible, the BER Analyzer does not calculate the performance parameters.
  
  What could be the reason for this issue?
  Is it related to the input signal type, the connection to the BER Analyzer, the simulation parameters (bit rate, sequence length, samples per bit), or a missing setting in the BER Analyzer?
  
  I would appreciate any suggestions or troubleshooting steps.
