Keysight N9935AU/356 Noise Figure Option

Overview

The Keysight N9935AU/356 Noise Figure Option uses the Y-Factor technique to accurately verify and characterize the noise figure of devices. It provides multiple measurement types, flexible setup configurations, and pre-configured measurement templates for common device types, with customizable uncertainty parameters to match specific measurement requirements.

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 templates: Amplifier, Downconverter, Upconverter, Multi-Stage Converter
• Customizable uncertainty contributions: Jitter uncertainty, ENR uncertainty, Mismatch uncertainty, User calibration uncertainty
• Uncertainty bars for measurement confidence visualization

Requirements

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