    I used the same target file you provided to me last time.

    Hi Damian,

    Thank you for your reply. By the way, is it possible to use multi mode fiber in your PAM direct detection. I tried to replace the Laser and SMF in your diagram with Spatial VCSEL, Parabolic-index MMF and Spatial PIN photo-diode. The BER Test Set gives me results, but the Electrical Constellation Visualizer seems not work well. Could you help me check my setting in the attached files.

    Thank you

    Hi Damian,

    Could you attach the target file again. There is no .dat file in the attachments. Also where I can see the symbol error rate and the error vector magnitude.

    Thanks
