Bit Error Ratio Test (BERT) Solution

Make the next leap forward with Keysight BERTs

Keysight offers the broadest choice of BERTs - covering affordable manufacturing test and high-performance characterization and compliance testing up to 32 Gb/s. NRZ and PAM4 coding scheme for 400G solution, Keysight's new flagship M8040A BERT solution capable of delivering a fully integrated 64Gbaud BER test. Combine with AWGs and M8070A BER system solution software. A revolutionary way for a BERT to perform device under test, with reliable and repeatable test results.

Keysight's Bit Error Ratio Test solutions allow the most accurate and efficient design verification, characterization, compliance and manufacturing test of high-speed communication ports for today's ASICs, components, modules and line-cards in the semiconductor, computer, storage and communication industry.

Keysight offers the broadest portfolio with four BERT families that address a variety of speed classes, usability concepts, and flexibility as well as application specific stimulus and analysis tools. All BERTs provide cost-effective and efficient in-depth insight into critical measurement tasks for today's and next generation devices with gigabit interfaces.

BERTs are used to test and characterize many high-speed digital interfaces:

QPI, FB-DIMM, PCI Express®, SATA,/SAS USB, Thunderbolt, DisplayPort, HDMI, MHL, MIPI, UHS-II, Fibre Channel, XAUI/10Gb Ethernet, CAUI/100GbE, CEI and other backplanes, XFI/XFP/SFP+/CFP modules, OTN, and PON-OLTs, Serdes, DAC, ADC, etc.
