Main characteristics and technical indicators
PAM-4 signals have data rates from 2 to 32 Gbaud and 64 Gbaud
Built-in de-emphasis and built-in analyzer equalization
Integrated and calibrated jitter injection: RJ, PJ1, PJ2, SJ, BUJ, and clock/2 jitter
Each module has two pattern generator channels for simulating the interference source channel
The pattern generator uses a remote probe front end to shorten the connection distance to the device under test
Real real-time PAM-4 error detection for low bit error rate
Algorithm PRBS, QPRBS and memory based pattern, pattern sequencer. For PAM4: Gray code, FEC encoding and precoder
All options and modules can be upgraded
description
Keep your 400G design under control
The Keysight M8040A is a highly integrated bit error rate tester (BERT) for physical layer characterization and compliance testing. With support for PAM-4 and NRZ signals and data rates up to 64 Gbaud (equivalent to 128 Gbit/s), it is suitable for all 200 and 400 GbE standards.
The M8040A BERT features true error analysis to provide accurate and repeatable measurements to optimize the performance margin of 400GbE devices.
Target application
Designed for R&D and test engineers, the M8040A helps them characterize chips, devices, transceiver modules and subassemblies, boards and systems. These devices and systems under test are primarily used in the data center and communications industries, with serial I/O ports with symbol rates up to 32 GBaud and 64 GBaud.
Many popular interconnect standards use the PAM-4 and NRZ data formats. The M8040A can perform receiver (input) tests on these standards as follows: 400 GbE, 50/100/200 GbE, OIF CEI-56G and CEI-112G, 64G/112G Fibre Channel, Infiniband-HDR, and interchip, A proprietary interface for chips and modules, backplanes, repeaters, and active fiber optic cables.
