    New 64 GBaud BERT Simplifies Accurate Characterization of PAM-4 and NRZ Devices

    Highlights:

    • 64 GBaud BERT for PAM-4 and NRZ
    • Streamlines receiver test setups with highly integrated pattern generator
    • Repeatable results with true PAM-4 error detection
    • Scalable and upgradeable for future needs
    • Extension of M8000 series of BER test solutions

    Keysight Technologies has introduced a M8040A high-performance BERT for testing PAM-4 and NRZ devices that operate up to 64 GBaud. Engineers in validation labs and R&D who characterize receivers on the physical layer for the next generation of data center interconnects will benefit from simplified test setups and repeatable and accurate results.

    Today’s data center infrastructure is continuously optimized to address bandwidth capacity growth, power, reach and service differentiation. Higher transmission rates, more transmission lanes and new multi-level data formats like PAM-4 address the increased transmission bandwidth demand for the next generation data center interconnects.

    The latest revisions of IEEE 802.3 bs and OIF CEI-56G implementation agreements define PAM-4 and NRZ interfaces for electrical chip-to-chip, chip-to-module, backplane connections and optical interfaces for up to 400 Gbit/s bandwidth. R&D and validation labs who need to characterize receivers for data center interconnects with PAM-4 or NRZ data rates up to 64 GBaud are facing new test challenges, such as tighter timing margins, channel loss, non-linearity, level interference and crosstalk effects—making test efficiency and accuracy essential.

    “The new 64 GBaud BERT for PAM-4 and NRZ extends our industry leading M8000 series for 400G,” said Jürgen Beck, vice president of Keysight’s Networks and Data Centers Solutions Business. “With its unique level of integration and scalability we enable R&D and test engineers to master the receiver test challenges for 400G data center interconnect.”

    The new M8040A is the latest member of the modular AXIe based M8000 series of BER test solutions. It is a highly integrated BERT that supports PAM-4 signals up to 64 GBaud and NRZ signals up to 64 Gbit/s. The pattern generator module provides built-in de-emphasis, jitter injection and an optional second channel. Engineers and designers can select PAM-4 and NRZ in the user interface, eliminating the need for external combiners and cabling provide PAM-4 signals. For best signal quality, remote heads reduce the distance to the device under test. The analyzer module provides true PAM-4 error analysis in real-time for long PRBS and QPRBS patterns. This allows proofing even low bit error ratios and symbol error ratios with the required confidence. Users can control the M8040A from a graphical and remote control interface.
