  • Characterizes 50/100/200 Gb/s Optical TX designs defined by IEEE 802.3cd
  • Key measurements include TDECQ, Optical Modulation Amplitude (Outer OMA), and Extinction Ratio (Outer ER)

Flexible and extensible

  • Run from a PC connected to an N109x DCA-M via USB
  • Automatic HTML report generation
  • Test all or selected parameters to compliance limits or custom limits


  • N1092X DCA-M Oscilloscope
  • N1077A Clock Recovery (Single-mode and Multimode)
  • N1078A Clock Recovery (Single-mode only)

The Keysight N1095BSCA Optical TX test application can be used with the N1092 DCA-M Series oscilloscopes to quickly and accurately perform optical TX PAM4 measurements according to:

  • IEEE 802.3bs 200 Gb/s and 400 Gb/s Optical TX (Sections 121, 122, 123, 124)

    • 200GBASE-LR4
    • 200GBASE-FR4
    • 200GBASE-DR4
    • 400GBASE-LR8
    • 400GBASE-FR8
    • 400GBASE-DR4
    • 400GBASE-SR16
  • IEEE 802.3cd 50 Gb/s, 100 Gb/s, and 200 Gb/s Optical TX (Sections 138, 139, 140)

    • 50GBASE-SR
    • 50GBASE-FR
    • 50GBASE-LR
    • 100GBASE-SR2
    • 100GBASE-DR
    • 200GBASE-SR4

The N1095BSCA is an easy-to-use optical TX test application that:

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

Key measurements include:

  • Transmitter and Dispersion Eye Closure (TDECQ)
  • Outer Optical Modulation Amplitude (Outer OMA)
  • Outer Extinction Ratio (Outer ER)
  • Average Optical Launch Power
  • Signaling Rate
  • Launch Power in OMAouter minus TDECQ
  • Transmitter Transition Time
  • Relative Intensity Noise (RINxx OMA) – FYI only

For a comprehensive and up-to-date list of specific tests covered by the application, download and install the N1095BSCA.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”.
