Keysight N9069C Noise Figure Measurement Application

Manufacturer: Keysight
Model Number: N9069C
The N9069C noise figure measurement application provides noise figure and gain measurements with multi-touch screen operation for the Keysight N9040B UXA Signal Analyzer. Transforming the UXA signal analyzer into noise figure analyzer, the application provides one-button noise figure and gain measurements to help you design, evaluate, and manufacture your devices or receiving systems. Characterize noise figure and gain of receivers and components (amplifiers and converters), in three views: graphic, meter and table. Achieve great testing flexibility with user-definable sweep time and noise source settling time settings. Achieve fully-specified measurements with an optional internal preamplifier up to 26.5 GHz on the UXA signal analyzer. Extend noise figure measurements up to 110 GHz with Keysight K-series block down converters (N8975AZ).


  • Signal analysis One-button noise figure and gain measurements on amplifiers, converters (including multi-stage converters) and receivers up to 50 GHz
  • Provides multi-DUT calibration routine and measurement profiles to speed up noise figure measurements on multiple DUTs
  • Supports Keysight SNS Series noise sources and 346 Series noise sources
  • Combine with U7227x Series USB preamps for reduced noise figure measurement uncertainty
  • Measurements include noise figure, gain, Y-factor, effective temperature, and hot/cold power density
  • Estimate the overall noise figure uncertainty using the measurement uncertainty calculator
  • To help optimize your measurements and minimize uncertainties, refer to the 10 Hints for Making Successful Noise Figure Measurements application note
