Perform transmitters with one-button noise figure and gain measurements with multi-touch UI operation.


  • Perform one-button noise figure and gain measurements from 10 MHz 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, 346 Series noise sources, U1831C USB smart noise source, and multi-stage converters, external LO control and manual mode
  • 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 using the measurement uncertainty calculator
  • Performance (hardware dependent)
    • Instrument noise figure: 17.25 dB at 1 GHz, 6.00 dB at 1 GHz with U7227A USB preamp
    • Instrument match: 1.52 at 1 GHz, 1.54 with U7227A USB preamp
  • Support multi-touch user interface and SCPI remote interface programming
  • KeysightCare software support subscription included
