Keysight N9952AU/356 Noise Figure Option

Overview

The N9952AU/356 Noise Figure option uses the Y-Factor technique to accurately verify and characterize the noise figure of devices. It provides comprehensive noise figure analysis with multiple measurement types, configurable setups, and pre-configured device under test (DUT) measurement profiles.

Key Features

• Five measurement types: Noise Figure, Noise Factor, Gain, Noise Temperature, and Y-Factor
• Four measurement setup types: Noise Source, DUT, Integration, and Uncertainty
• Four pre-configured DUT measurement types: Amplifier, Downconverter, Upconverter, and Multi-Stage Converter
• Customizable uncertainty contribution values for device-specific analysis
• Y-Factor technique for accurate characterization

Customizable Parameters

• Jitter uncertainty
• ENR uncertainty
• Uncertainty bars
• Mismatch uncertainty
• User calibration uncertainty

Requirements

• Spectrum Analyzer Mode (Option 233 on combination models)
• Internal Preamplifier (Option 235)
• DC Bias Variable Voltage Source (Option 309)
• CPU2 processor
• External noise source (Keysight models 346A/B/C/K40/K01 supported)
• Optional: External preamplifier (Keysight models U7227A/C/F or U7228A/C/F)
• Accessory: N9910X-713 BNC to SMB cable

Applications

• Amplifier noise figure characterization
• Downconverter and upconverter analysis
• Multi-stage converter noise performance
• Device qualification and performance validation
