M8040A High-Performance
BERT 64 Gbaud
Version 10.5
Master your next design
Introduction
The Keysight Technologies Inc. M8040A is a highly integrated BERT for physical layer characterization and compliance testing.
With support for pulse amplitude modulation 4-level, 3-level (PAM4, PAM3) and non-return-to-zero (NRZ) signals, and symbol rates up to 64 Gbaud (corresponds to 128 Gbit/s) it can be used for testing devices designed for 400/ 200 GbE, 800G, OIF CEI-56G and CEI-112G, PCIe ® 64/32/16/8/5 GT/s, USB4 Version 2,0, USB 3.2, USB4, Thunderbolt™ 3 and Thunderbolt™ 4.
The M8040A BERT´s true error analysis provides repeatable and accurate results, optimizing the performance margins of your devices.
Key features
Applications
The M8040A can be used for receiver (input) testing for many emerging interconnect standards, such as:
M8000 Series of BER Test solutions
Simplified time-efficient testing is essential when you are developing next-generation computer, consumer, or communication devices
The Keysight M8000 Series is a highly integrated BER test solution for physical layer characterization, validation, and compliance testing.
With support for a wide range of data rates and standards, the M8000 Series provides accurate, reliable results that accelerate your insight into the performance margins of high-speed digital devices.
M8040A High-performance BERT 64 Gbaud
Simplifies accurate receiver characterization of devices operating up to 32 and 64 Gbaud with NRZ, PAM3 and PAM4 signals
Highest level of integration streamlines receiver test setups
With the M8040A, all critical test capabilities for input/receiver (RX) characterization are built in. The pattern generator module provides calibrated and integrated jitter sources and de-emphasis to emulate the transmitter (TX) and to compensate for channel loss in the test setup. In addition, the M8040A provides an internal clock synthesizer and a second pattern generator output channel to emulate an aggressor lane.
The analyzer provides true PAM4 and NRZ error analysis in real time and full sampling to measure down to very low BER and SER.
This high level of integration with the M8040A makes the receiver test set-up connections easier and more robust. Setup and debug time are shortened, calibration is simpler, and the frequency of re-adjustments is reduced, resulting in a more efficient use of overall test time.
Repeatable and Accurate Results with M8040A
The M8040A high-performance BERT provides clean NRZ, PAM3 and PAM4 signals up to 64 Gbaud with fast transitions and low intrinsic jitter. The remote head concept of M8040A with the short 1.85 mm cables brings the performance close to the device under test, minimizing signal degradations caused by lossy channels.
