The Keysight (formerly Agilent) N8976B is a high-performance noise figure analyzer designed for fast, accurate, and repeatable noise figure measurements across a broad frequency range. Its versatile capabilities extend from 10 MHz to 40 GHz in a single unit, with the potential to reach up to 110 GHz using specialized block downconverters. The instrument features a multi-touch interface, enhancing usability with intuitive gestures for navigation and control. Beyond its primary function, the N8976B integrates Spectrum Analyzer and IQ Analyzer (Basic) modes, providing additional analytical capabilities for characterizing DUTs.
The N8976B is engineered for efficiency, offering features such as automatic download of noise source and USB preamplifier data (ENR data) when used with compatible Keysight SNS Series noise sources and U7227 Series USB preamplifiers. This integration, along with a built-in noise figure uncertainty calculator, streamlines measurements and minimizes uncertainty by pre-populating data for the analyzer, noise source, and USB preamplifier. The analyzer supports streamlined noise source calibrations for Y-Factor measurements, allowing combined calibrations for up to 12 DUT setups in a single step. Furthermore, an internal calibration feature reduces test time by eliminating the need for user calibration for many DUT types. The instrument is capable of simultaneous noise figure and gain measurements, and can display various measurement results, including Noise Figure, Noise Factor, Y-Factor, Gain, Phot, Pcold, and Teffective in a tabular format.
