Keysight N9953BU/356 Noise Figure Measurement Option

Overview

The Keysight N9953BU/356 option uses the Y-Factor technique to accurately verify and characterize the noise figure (NF) of RF devices. This option supports multiple measurement types and pre-configured DUT measurement setups for 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 your device
• Support for Keysight noise sources (models 346A/B/C/K40/K01)
• Compatible with external preamplifiers (Keysight models U7227A/C/F or U7228A/C/F)

Customizable Uncertainty 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)
• BNC to SMB cable (accessory N9910X-713) for DC bias connection
