Comprehensive measurement and debug solution

  • Characterizes 100/200/400 Gb/s TX designs defined by IEEE802.3ck
  • Performs nearly 140 tests
  • Key measurement includes 12-edge Output Jitter (Jnu, JRMS, EOJ), SNDR & Eye-opening (EH, EW, VEC)

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 compliance limits or custom limits


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

The Keysight N1091CKCA TX test application can be used with the N1000A DCA-X oscilloscopes to quickly and accurately perform PAM4 measurements according to:

  • IEEE 802.3ck 100Gb/s, 200 Gb/s and 400 Gb/s Operation

    • 100GAUI-1, 200GAUI-2 and 400GAUI-4 Chip-to-Chip (C2C) TX characteristics
    • 100GAUI-1, 200GAUI-2 and 400GAUI-4 Chip-to-Module (C2M) host/module output characteristics
    • Transmitter characteristics, 100GBASE-CR1, 200GBASE-CR-2, and 400GBASE-CR4
    • Transmitter characteristics, 100GBASE-KR1, 200GBASE-KR-2, and 400GBASE-KR4 

The N1091CKCA 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 Jnu, JRMS, and EOJ on “12-edges” 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 Width, Eye Height & Vertical Eye Closure
  • Effective Return Loss

For a comprehensive and up-to-date list of specific tests covered by the application, download and install the N1091CKCA .exe onto a PC (click the Trials and Licenses tab), and run the application in “Demo Mode”. No license (or hardware) is required to run the software application in “Demo Mode”.
