Keysight’s FieldFox is the world’s most integrated handheld RF and microwave analyzer and now includes Noise Figure (NF) measurements. The FieldFox family of handheld microwave analyzers with noise figure (NF) mode Provides po
rtable one-button noise figure and gain measurements to help design engineers characterize devices including low noise amplifiers (LNAs), frequency converters, and receivers using the industry proven Y-factor technique. FieldFox noise figure measurements can be used to quantify the degradation in signal-to-noise ratio caused by components in communications systems.
Communication system capacity is limited by internally generated noise. This noise will impact link budget, increase investment on the transmitter design, or increase the antenna cost at the receiver. One of the key performance indicators for a receiver is
its sensitivity, which is close to the noise floor.
The performance of a communication system is also based on signal-to-noise ratio (SNR). While vector network analyzer S-parameter measurements, spectrum analyzer, channel power, and adjacent channel power measurements, additional evaluation of internally generated noise is necessary. As such, noise figures can be used to quantify the degradation in SNR caused by components in the link.
Transforming the Keysight FieldFox handheld microwave analyzer into noise figure (NF) mode Provides portable one-button noise figure and gain measurements to help characterize devices including low noise amplifiers (LNAs), frequency co
nverters, and receivers using the industry proven Y-factor technique. FieldFox can also provide real-time feedback on measurement integrity with built-in uncertainty bars that can be displayed on the measurement data. By combining noise figure measurements with full 2-port vector network analysis, spectrum analysis, and power sensor integration, FieldFox can now provide complete characterization of amplifiers and converters in the field or repair depots.
Key Features
- Portable Y-factor noise figure measurements for characterization of amplifiers and frequency converters
- One-button measurements for noise figure, noise factor, gain, noise temperature, Y-factor
- Auto integration mode optimizes gain and avoid jitter goal

The FieldFox family provides a choice of 22 combination (combo) and spectrum analyzer models with frequency coverage from DC to 50 GHz and users can configure combo models to include spectrum analyzer, VNA, CAT, Noise Figure (NF), RTSA, and more. All models offer benchtop precision and are MIL-Class 2 rugged.
FieldFox noise figure (NF) mode software is available on FieldFox combo and spectrum analyzer models. Users can upgrade the analyzer with the use of a software license key.
