Agilent/Keysight E4866A

The Keysight E4866A is a serial BERT module for the ParBERT 81250 system, designed to generate and analyze differential or single-ended signals at data rates from 9.5 to 10.8 Gbit/s. This VXI slot-wide module provides signal generation and analysis capabilities for high-speed serial interface testing and characterization across 10 Gigabit Ethernet, OC-192, and OC-768 applications.

• Sub-20 ps transition times for accurate edge characterization
• Low jitter generation and analysis
• ECL-level detection and clock recovery

– Typical Applications

• 10-Gigabit Ethernet at 10.3 Gbit/s and 9.953 Gbit/s
• OC-768/STM-256 parallel side testing (4×10.8 Gbit/s)
• OC-192/STM-64 parallel side (1×10.8 Gbit/s) and serial side (16×675 Mbit/s)
• Multi-device concurrent manufacturing test

– Compatibility & Integration

The E4866A integrates into the ParBERT 81250 system as a dedicated serial BERT module. Generator operation requires the N4868A booster module. The module supports both single-ended and differential signal modes, enabling flexible test configurations for modern telecommunications and data center applications.
