Keysight N9961AU/356 Noise Figure Option

Overview

The Keysight N9961AU/356 Noise Figure Option uses the Y-Factor technique to accurately verify and characterize the noise figure performance of RF and microwave devices. This option provides comprehensive noise analysis capabilities with multiple measurement types, setup configurations, and pre-configured device measurement profiles to streamline testing workflows.

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 including jitter, ENR, mismatch, and user calibration uncertainty
• Support for Keysight noise source models 346A/B/C/K40/K01
• Optional external preamplifier support (Keysight U7227A/C/F or U7228A/C/F)

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 (compatible Keysight models)
• BNC to SMB cable (N9910X-713) for DC bias connection

Applications

• Noise figure characterization of amplifiers and converters
• Device quality assessment and verification
• RF and microwave system design validation
• Production testing and quality control
