The Keysight N9914A FieldFox is a handheld RF combination analyzer built for field testing, spectrum monitoring, and cable/antenna characterization. The base model delivers Distance-to-Fault, return loss, cable loss, and VSWR measurements across 30 kHz to 6.5 GHz. Its modular architecture supports optional vector network analysis, spectrum analysis, power metering, vector voltmeter, noise figure, real-time spectrum analysis, and GPS geo-location tagging—enabling a single portable instrument to handle routine maintenance through advanced troubleshooting. The instrument meets MIL-SPEC durability standards with a dust-free, vent-free design. Its transflective display and backlit keys provide reliable readability from direct sunlight to low-light field conditions. Type-N female RF connectors and 50 Ω input impedance ensure compatibility with standard test equipment.
