The new Tektronix real-time instrument based OIF-CEI-56G-VSR, OIF-CEI-56G-MR, and OIF-CEI-56G-LR Transmitter Characterization automation system provides turnkey testing and debug of the industries most common 400G PAM4 electrical interfaces. The silicon designers need to perform the 400G based electrical validation of their silicon; the system designers need to perform the 400G based electrical validation. These tools are brought together in a single 400G-TXE package.

Key Features
  • 400G-TXE offers streamlined and fully automated transmitter characterization of OIF-CEI-56G-VSR, OIF-CEI-56G-MR, and OIF-CEI-56G-LR electrical transmitter specifications.
  • Extends PAM4 software package for in-depth analysis and debug of fully automated OIF-CEI-56G-VSR, OIF-CEI-56G-MR, and OIF-CEI-56G-LR conformance test solution.
Applications

 

  • Validation of OIF-CEI-56G-VSR, OIF-CEI-56G-MR, and OIF-CEI-56G-LR standards
  • Measurements of electrical transmitter

OIF-CEI-56G-VSR, OIF-CEI-56G-MR, and OIF-CEI-56G-LR fully automated electrical transmitter real-time oscilloscope measurements

This application package is designed in conjunction with the performance levels offered by a 50 GHz, 70KSX instrument pair. The 400G-TXE loads the required Bessel Thomson roll-off filter, which constrains the channel-out to the specification mandated 40 GHz point. This is common across all OIF 400G electrical specifications in the industry today. The unique lower noise level of the ATI architecture serves the key signal-to-noise and distortion ratio measurements, which are attained with margin on the 70KSX systems. The 400G-TXE solution is also available on a non-70KSX systems, such as 33 GHz, higher 70KDX, and MSO instruments with an understanding that these are for debug only and not for the specification level conformance validation.

Electrical system interconnect setup

Direct electrical connections via a precision fixture or 2.92 mm interconnects are the preferred method to access the backplane and cabled signals. The QSFP28 module interconnect point found on the 400G-TXE design is the most typical signal access point.

User-defined mode

In user-defined mode, users can configure Global parameters, test specific parameters, measurement repeat parameters, and notification parameters. This supports characterization of measurements rather than developing custom lab setups, reducing the testing time and complexity.
