Master your next design

The Keysight M8040A is a highly integrated BERT for physical layer characterization and compliance testing. With support for PAM4 and NRZ signals and data rates up to 64 Gbaud (corresponds to 128 Gbit/s) it can be used for characterizing the receiver performance margins on the physical layer for popular high-speed digital interface standards, such as 400G Ethernet, PCI Express 5, TBT 3.

The M8040A BERT offers true error analysis and provides repeatable and accurate results optimizing the performance margins of your devices.

Target Applications

The M8040A is designed for R&D and test engineers who characterize chips, devices, transceiver modules and sub-components, boards and systems with serial I/O ports operating with data rates up to 32 Gbaud and 64 Gbaud in the server, computing, data center and communications industry.

The M8040A can be used for receiver (input) testing for many popular interconnect standards that use PAM4 and NRZ data formats, such as: PCIe 5, TBT3, 400 GbE, 50/100/200/400/800 GbE, OIF CEI-56G and CEI-112G, 64G/112G Fibre Channel, Infiniband-HDR and proprietary interfaces for chip-to-chip, chip-to-module, backplanes, repeaters and active optical cables.

M8040A 64 GBaud high-performance BERT, 400G, accurate characterization of 400 GbE PAM-4 & NRZ devices

The pattern generator of the M8040A Gbaud BERT provides a clean 26.5625 Gbaud PAM4 output signal.
