The Agilent/Keysight N4901B is a serial Bit Error Rate Tester (BERT) for validation and characterization of high-speed digital interfaces. It generates and analyzes serial data streams to measure bit error rates with precision, supporting extensive PRBS pattern libraries (PRBS7, PRBS15, PRBS23, PRBS31) and user-defined patterns. The instrument detects single-bit and multi-bit errors with high-resolution counting and provides jitter generation across multiple types - random, deterministic, sinusoidal, and aliased - to stress-test receiver tolerance.
Advanced clock recovery locks onto incoming data with varying jitter content, while configurable output amplitude and rise/fall times simulate diverse signal conditions. Built for both R&D and manufacturing, the N4901B delivers signal integrity analysis including eye diagrams, rise/fall time measurements, and amplitude characterization. Its variable input sensitivity and quantifiable jitter tolerance masks support interoperability testing across communication systems and standards-compliant validation workflows.
