Product Status: Discontinued | Currently Supported
This product is no longer available

A replacement for this product is available:

Key Features & Specifications

The M9069A 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 6 GHz with M9391A, 10 MHz to 3.6 GHz with M9393A
  • Supports Keysight 346 Series noise source (346CH08 USB adapter is required to connect to BNC-input-bias noise source the USB controller port)
  • Combine with U7227x Series USB preamps for reduced noise figure measurement uncertainty
  • Compatible with M9391A PXIe VSA and M9393A PXIe Performance SA


  • 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 the 10 Hints for Making Successful Noise Figure Measurements application note
  • Support for multi-stage converters, external LO control and manual mode

Other features

  • License key upgradeable
  • Transportable software license supports up to four PXIe VSAs in one mainframe
  • SCPI remote interface, code compatible with ESA, PSA, and NFA


The M9069A noise figure measurement application is one in a common library of measurement applications for the Keysight modular PXIe VSAs, transforming them into noise figure testers with convenient one-button operation, automating measurement procedures, and allowing you to stay on the leading edge of your design and manufacturing challenges.

Noise figure measurements

  • Characterize noise figure and gain of receivers and their lower-level components, in three data views: graphic, meter and table
  • Achieve great testing flexibility with user-definable sweep time and noise source settling time settings
