Keysight N9915AU/356 Noise Figure Option

Overview

The N9915AU/356 Noise Figure Option uses the Y-Factor technique to accurately verify and characterize the noise figure of devices. It supports measurement of amplifiers, downconverters, upconverters, and multi-stage converters with customizable uncertainty parameters for precise analysis.

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 types: Amplifier, Downconverter, Upconverter, Multi-Stage Converter
• Customizable uncertainty contribution values
• Y-Factor technique for accurate measurements

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 supported)
• Optional external preamplifier (Keysight models U7227A/C/F or U7228A/C/F) recommended for improved accuracy
• Accessory N9910X-713 BNC to SMB cable for DC bias connection
