Keysight recently announced innovative enhancements for the M8040A high-performance bit error ratio tester (BERT) solution 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 emerging 400G data center interconnects will benefit from simplified test setups and repeatable and accurate results.
The new M8040A is the latest member of the modular AXIe-based M8000 Series of BER test solutions and 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 by software in the user interface, eliminating the need for external combiners, cabling and deskew to 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—allowing proofing even low-bit error ratios and symbol error ratios with the required confidence.
The error analyzer now supports symbol rates up to 64 Gbaud for NRZ signals and built-in adjustable equalization. Users can control the M8040A from a graphical and remote-control interface.
