The Keysight N109256CB TX test application can be used with the N1000A/86100D DCA-X or N109X DCA-M Series oscilloscopes to quickly and accurately perform NRZ and PAM4 measurements according to:

• CEI-56G-VSR (Reference OIF2014.277.08 NRZ, OIF-CEI-4.0 PAM4)
  • Section 15.3.2 Host to Module at TP1a, Table 15-1 (NRZ)
  • Section 15.3.3 Module to Host at TP4, Table 15-4 (NRZ)
  • Appendix 15.B.1.1 Host-to-Module at TP0a, Table 15.9 (NRZ)
  • Section 16.3.2 Host to Module at TP1a (Host Output), Table 16-1 (PAM4)
  • Section 16.3.3 Module to Host at TP4 (Module Output), Table 16-4 (PAM4)
  • Appendix 16.B.1.1 Host to Module at TP0a, Table 16.10 (PAM4)
• CEI-56G-MR (Reference OIF-CEI-4.0)
  • Section 17.3.1, Table 17-2 and 17-3 (MR-PAM4)
• CEI-56G-LR (Reference OIF-CEI-4.0)
  • Section 21.3.1, Tables 21-2, 21-3 (LR-PAM4)

The N109256CB is an easy-to-use TX test application that:

• Saves time in understanding details of standards
• Reduces the time it takes to characterize your PAM4 and NRZ design from hours to minutes
• Helps debug your device using custom configurations
• Allows you to quickly generate HTML reports that summarize the performance of your device

Key measurements include:

• Jitter Measurements including UUGJ, BUJ, Even-Odd Jitter (EOJ)
• Output Waveform measurements including Steady-State Voltage (Vf), Linear Fit Pulse Peak and Signal-to-Noise-and-Distortion (SNDR)
• Transition Time
• Eye Width (EW6) and Eye Height (EH), Far-end and Near-end
• Return Loss
