Keysight’s VNA noise figure uncertainty calculator is the most comprehensive tool in the industry for estimating errors in noise figure measurements. Due to the VNA’s advanced noise figure error-correction methods which provide industry-leading accuracy, and unlike other uncertainty calculators which ignore key contributions to error, Keysight’s Monte-Carlo-based VNA noise figure uncertainty calculator provides estimates of errors due to the following contributions:

  • Mismatch error resulting from residual S-parameter uncertainty
  • Noise-parameter-induced error resulting from DUT input-noise interaction with imperfect system-source match
  • Noise-source ENR or power-meter uncertainty
  • Noise-receiver linearity, compression, jitter, and temperature drift

The VNA noise figure uncertainty calculator runs on a VNA or an external Windows®-based PC. It is limited to amplifier measurements using the low-noise receiver provided with Option 029. Both vector and scalar noise calibrations are supported, as well as characterization of the noise receiver using a noise source or power meter. It requires Keysight’s VEE Runtime application, which is factory-installed on VNA units, or available for external PCs here.

Keysight recommends using the most current version, which includes the most up-to-date bug fixes and security patches available.
