VNA Noise Figure Uncertainty Calculator
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.
