As the demand for faster, more reliable digital interfaces grows, engineers need high-performance Bit Error Ratio Testers (BERTs) that not only meet today’s standards but are also future-ready.
That’s where Keysight’s M8050A and M8040A dominate the competition.
M8050A
The Benchmark for 800G/1.6T, PCIe Gen6 & USB4 Testing
- PCIe Gen7-Ready – The ONLY BERT capable of PCIe Gen7 testing, making it the best investment for future compliance.
- One solution – Unlike competitors, Keysight covers RX, TX, channel testing, and automation software in a single ecosystem.
- Fully Upgradable – On-site AXIe module and software license upgrades let users scale as needs evolve.
- Integrated Accessories – Includes remote heads, ISI channels, redrivers, and RX test automation software for a turnkey solution.
If you are working with PCIe, USB4, or ultra-high-speed digital interfaces, the M8050A is the ultimate choice for scalability, precision, and long-term value.
M8040A
Versatility Across PCIe, USB, 400G/800G & More
- Supports PCIe Gen1-Gen6, USB, SATA, SAS, DP, MIPI M-PHY, and PON – A truly universal BERT for multi-protocol testing.
- Industry-First Single-Vendor Solution – The only BERT covering RX, TX, and protocol testing with ISI channels, redrivers, and automation software.
- Future-Proof Investment – On-site upgradable AXIe modules ensure long-term adaptability.
- Built for Real-World Conditions – Includes interference sources to simulate actual high-speed data environments.
For flexible, multi-standard testing, the M8040A delivers unmatched value and performance, eliminating the need for multiple fragmented solutions.
