Keysight extends PAM-4 measurement solution support
PAM-4 support and the ability to integrate a device’s built-in error counter helps R&D and test engineers characterize and test high-speed digital receivers for the data-center networking, storage and computer industries.
R&D and validation teams characterizing next-generation digital designs face several test challenges. With data rates continuously increasing, emerging data center standards like OIF CEI and IEEE 802.3 Ethernet are moving to PAM-4 multilevel signaling formats. In addition, many ASIC designs now use built-in self-test (BIST) capabilities such as built-in error counters. Engineers can typically access the error-count information only through vendor-specific interfaces and remote commands.
The M8000 Series BER test solution accelerates insight into digital designs with fast and accurate receiver characterization for single- and multilane devices. The test solution consists of AXIe-based high-performance BERT and arbitrary waveform generator modules that are controlled from common user interface software. Using the M8070A system software, rev. 188.8.131.52, for the M8000 Series, engineers can now:
Generate PAM-4 patterns up to 32 Gbaud symbol rate (corresponds to a 64 Gbit/s bit rate) and up to 4 channels with the M8195A arbitrary waveform generator, and NRZ patterns with the J-BERT M8020A high-performance BERT from a common user interface
Accelerate test efficiency by integrating access to built-in error counters and device status registers from the M8000 user interface via IronPython scripts
For accurate PAM-4 device characterization and simulation, Keysight offers several complementary test instruments and software solutions. The solutions include the J-BERT M8020A, M8195A arbitrary waveform generator, N5990A test automation software, M8062A 32-Gb/s BERT front end, Infiniium Z-Series oscilloscopes and 86100D Infiniium DCA-X high-bandwidth oscilloscope with Option 9FP. Also included is the N8827A PAM-4 analysis software for Infiniium real-time oscilloscopes and Advanced Design System electronic design automation tools.
