Keysight M8040A High-Performance BERT Getting Started Guide

1

Introduction

Introduction

The Keysight Technologies M8040A is a highly integrated BERT for

physical layer characterization and compliance testing.

With support for pulse amplitude modulation 4-level (PAM-4) and

non-return-to-zero (NRZ) signals, and symbol rates up to 64 GBaud

(corresponds to 112 Gbit/s) it covers all flavors of the emerging 400 GbE

and CEI-56G standards.

The M8040A BERT´ s true error analysis provides repeatable and accurate

results, optimizing the performance margins of your devices.

Key Features

The M8040A provides the following features:
• Data rates from 2 to 32 and 64 GBaud
• PAM4, PAM3 and NRZ selectable from M8070B user interface
• Built-in 5 tap transmitter FFE with multiple presets to compensate loss
• Integrated and calibrated jitter injection: RJ, LF and HF PJ (multi-tone,

sinusoidal), BUJ, clk/2 jitter, sRJ, rSSC, and SSC

• Forward Error Correction (FEC) encoding and error insertion for testing

DUTs with FEC decoder

• Two pattern generator channels per module to emulate aggressor lane
• Linearity tests with adjustable PAM4 and PAM3 levels
• Interactive link training 2.5/5/8/16/ 32 GT/s PCI Express®
• Interactive link training for USB 3.2, 5 Gb/s and 10 Gb/s, x1 and x2
• SKP OS filtering for 2.5/ 5/ 8/ 16/ 32 64 GT/s PCI Express® and SKP

OS filtering for USB 3.2

• Short connections to the DUT with remote heads for the pattern

generator

• True PAM-4 error detection in real-time for low BER levels
• Built-in and adjustable equalization to re-open closed eyes
• Integrated clock recovery and control of external clock recovery units

N1076A/B, N1077A, N1078A

• RI and SI level interference injection via M8054A interference source for

M8194A/95A/96A AWG

• Graphical user interface and remote control via M8000 system software
• Scalable and upgradeable with options and modules
