The Keysight N9912A FieldFox Handheld RF Analyzer consolidates spectrum analysis, vector network analysis, and cable/antenna testing into a single 6.2 lb portable instrument. Operating from 2 MHz to 4 GHz (upgradeable to 6 GHz), it delivers field-grade measurements without requiring external calibration kits. The N9912A executes return loss, distance-to-fault, VSWR, insertion loss, S-parameters, channel power, occupied bandwidth, and pulse power analysis in a task-driven interface built for demanding field environments.
