Key Features & Specifications

The N9069C is discontinued after June 1, 2019. The replacement model is the N9069EM0E X-Series Measurement Application with KeysightCare.

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

Performance (hardware dependent)

  • Instrument noise figure: 12.25 dB at 1 GHz, 5.45 dB at 1 GHz with U7227A USB preamp
  • Instrument match: 1.45 at 1 GHz, 1.54 with U7227A USB preamp

Other features

  • License key upgradeable
  • Fixed and transportable license available
  • Programmable via USB, LAN or GPIB, code compatible with ESA, PSA and NFA


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.

Noise figure measurements

  • 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)
