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
• PAM-4 and NRZ selectable from M8070A user interface
• Built-in 4 tap de-emphasis to compensate loss
• Integrated and calibrated jitter injection: RJ, PJ1, PJ2, SJ, BUJ, and
even-odd jitter
• Two pattern generator channels per module to emulate aggressor
• Linearity tests with adjustable PAM-4 levels
• Short connections to the DUT with remote heads for the pattern
generator
• True PAM-4 error detection in real-time for low BER levels
• Graphical user interface and remote control via M8000 system software
• Scalable and upgradeable with options and modules
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 data center and communications industries.
The M8040A can be used for receiver (input) testing for many popular
interconnect standards, such as:
• 400 Gigabit Ethernet (IEEE 802.3bs)
• 200/100/50 Gigabit Ethernet
• OIF CEI - 56G (NRZ and PAM-4 versions)
