Keysight N9951AU/356 Noise Figure Option

Overview

The N9951AU/356 Noise Figure Option enables accurate verification and characterization of the noise figure of devices using the Y-Factor technique. This option supports multiple measurement types and pre-configured setups for different device categories including amplifiers, downconverters, upconverters, and multi-stage converters.

Key Features

• Five measurement types: Noise Figure, Noise Factor, Gain, Noise Temperature, Y-Factor
• Four measurement setup types: Noise Source, DUT, Integration, Uncertainty
• Four pre-configured DUT measurement types: Amplifier, Downconverter, Upconverter, Multi-Stage Converter
• Customizable uncertainty contribution values for device-specific calibration
• Support for external Keysight noise sources and preamplifiers

Applications

• Noise figure characterization of RF amplifiers
• Downconverter and upconverter testing
• Multi-stage converter noise analysis
• Device verification and acceptance testing
