Keysight N9935BU/356 Noise Figure

Overview

The Keysight N9935BU/356 Noise Figure option uses the Y-Factor technique to accurately verify and characterize the noise figure of RF devices. The option supports multiple measurement types and pre-configured device measurement setups, with customizable uncertainty contributions for precise characterization of 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 parameters: jitter, ENR, mismatch, and user calibration
• Uncertainty bars for measurement confidence visualization

Applications

• Low-noise amplifier characterization
• Receiver front-end verification
• Converter and mixer noise performance testing
• Device quality assurance and compliance

Included Accessories

• N9910X-713 BNC to SMB cable for DC bias connection
• Compatible with Keysight noise sources: 346A/B/C, K40, K01
• Recommended external preamplifiers: U7227A/C/F, U7228A/C/F
