The Keysight N109212CA TX test application can be used with the N1000A DCA-X oscilloscopes to quickly and accurately perform PAM4 measurements according to:

  • CEI-112G-VSR (Reference OIF-2017.346.22 PAM4)
    • Section 25.3.2 Host-To-Module at TP1a, Table 25-1
    • Section 25.3.3 Module-to-Host at TP4, Table 25-4
    • Appendix 25.C.2 Host-to-Module at TP0a, Table 25-15
  • CEI-112G-MR-PAM4 (Reference OIF-CEI-05.0)
    • Section 26.3.1 Table 26-3 and 26-4 (MR-PAM4)
  • CEI-112G-LR-PAM4 (Reference OIF-CEI-05.0)
    • Section 27.3.1 Table 27-3 and 27-4 (LR-PAM4)

The N109212CA 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 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 EOJ, J3/4/5U, JRMS of a PRBS13Q
  • Output Waveform measurements including Steady-State Voltage (Vf), Linear Fit Pulse Peak and Signal-to-Noise-and-Distortion (SNDR)
  • Transition Time
  • Eye Height, Vertical Eye Closure, Near-End & Far-End Eye measurement
  • Return Loss

Comprehensive measurement and debug solution

  • Characterizes CEI-112G-VSR/MR/LR TX designs defined by OIF-CEI-112G
  • Performs over 100 tests
  • Key measurement includes jitter, SNDR, Vertical Eye Closure, eye linearity and return loss

Flexible and extensible

  • Operates on an N1000A DCA-X oscilloscope, or on a PC connected to an N1000A DCA-X via LAN
  • Automatic HTML report generation
  • Test all or selected parameters to conformance limits or custom limits


  • N1000A DCA-X mainframe
  • N107x Clock Recovery
  • N104xA/B Remote head
