The Keysight N9952B FieldFox is a handheld microwave analyzer that combines cable and antenna testing, vector network analysis, and spectrum analysis into a single field-deployable instrument. Operating from 9 kHz to 50 GHz, it delivers measurement accuracy and dynamic range required for RF validation in telecommunications, aerospace, defense, and satellite applications. The ruggedized design supports field operation across –10 to +55 °C with dust and splash protection per MIL standards, while the 6.5-inch transflective color display and field-swappable lithium-ion battery enable extended troubleshooting sessions in demanding environments.
