This product is no longer available

A replacement for this product is available:

Key Features & Specifications

The W9069A is discontinued after June 1, 2019. The replacement model is the N9069EM0D X-Series Measurement Application with KeysightCare.

Signal analysis

  • One-button noise figure and gain measurements from 10 MHz to 26.5 GHz
  • Supports Keysight SNS Series noise sources and 346 Series noise sources
  • Combine with U7227x Series USB preamps for reduced noise figure measurement uncertainty
  • Runs inside the CXA signal analyzer


  • Measurements include noise figure, gain, Y-factor, effective temperature, and hot/cold power density
  • Estimate the overall noise figure using the measurement uncertainty calculator
  • To help optimize your measurements and minimize uncertainties, refer to "10 Hints for Making Successful Noise Figure Measurements" application note
  • Support for multi-stage converters, external LO control, and manual mode


  • Instrument noise figure: 10.4 dB at 1 GHz, with preamp on
  • Instrument match: 1.50 at 1 GHz, with preamp on

Other features

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


The W9069A noise figure measurement application for the CXA is one in a common library of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. Transforming the CXA signal analyzer into noise figure measurements, 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 their lower-level components, in three data views: graphic, meter and table
  • Achieve greater testing flexibility with user-definable sweep time and noise source settling time settings
  • Achieve noise figure measurements with an optional internal preamplifier up to 26.5 GHz on the CXA signal analyzer
