Description
Overview
The Keysight M8050A is a high-performance bit error rate tester (BERT) module designed for testing serial I/O ports operating at data rates up to 120 GBd. It supports multiple modulation formats including PAM4 and PAM8, making it ideal for next-generation communication systems, servers, and data center applications. The module offers integrated jitter injection, de-emphasis, and real-time error analysis with built-in clock recovery and powerful equalization.
Key Features
- Symbol rates from 2 to 120 GBd with flexible modulation support (NRZ, PAM3, PAM4, PAM6, PAM8)
- Built-in 7-tap de-emphasis for channel loss compensation
- Transition time less than 5 ps with intrinsic random jitter below 100 fs RMS
- Integrated and calibrated jitter injection (RJ, PJ1, PJ2, BUJ, sRJ, clock/2)
- Real-time error analysis up to 64 Gbaud PAM4 with integrated clock recovery
- Software-upgradeable functionality for extended capability
Applications
- Serial I/O port testing for servers and computing systems
- Data center communication system characterization
- Receiver and transmitter testing with Keysight UXR-Series oscilloscopes
- Compliance testing for high-speed serial standards
