Keysight N9914AU/356 Noise Figure Option

Overview

The Keysight N9914AU/356 Noise Figure Option provides accurate characterization of device noise performance using the industry-standard Y-Factor measurement technique. This option supports multiple measurement types and pre-configured device categories, with customizable uncertainty contributions for precise noise analysis in amplifiers, converters, and multi-stage systems.

Key Features

• Five measurement types: Noise Figure, Noise Factor, Gain, Noise Temperature, and Y-Factor
• Four setup types: Noise Source, DUT, Integration, and Uncertainty
• Four pre-configured DUT measurement profiles: Amplifier, Downconverter, Upconverter, and Multi-Stage Converter
• Customizable uncertainty contributions including jitter, ENR, mismatch, and user calibration uncertainty
• Graphical uncertainty bar display for confidence assessment
• Supports external Keysight noise sources and preamplifiers

Applications

• Amplifier noise performance verification and characterization
• Downconverter and upconverter noise measurement
• Multi-stage receiver system noise analysis
• Design validation and optimization of low-noise circuits
• Compliance and specification validation for RF devices
