The Keysight (formerly HP) 3764A is a high-performance digital transmission analyzer designed for comprehensive error performance testing of telecom and digital transmission systems. It operates primarily at 140 Mb/s with features including pattern generation and error detection at both coded and binary interfaces. Equipped with an HP-IB interface as standard, the analyzer is available with options for multiple CEPT bit-rates (Option 001) and jitter generation/measurement (Option 002), making it highly versatile for field installation, maintenance, development, and manufacturing applications.
